This document discusses carbon bonding and the formation of carbon compounds. It explains that carbon can form strong covalent bonds with other carbon atoms through a process called catenation, allowing it to form straight chains, branches, and rings. This bonding ability arises because carbon is tetravalent and can hybridize its orbitals, taking on different hybridization states like sp, sp2, and sp3. Some carbon compounds exhibit resonance, where electrons are delocalized over multiple carbon atoms. This results in more stable structures that are hybrids of different resonant forms. Overall, carbon's unique bonding properties allow it to form a diverse array of stable organic compounds.

Please write TRUE or FALSE for each of the 8 statements.
Thank you! Mark the following statements about carbon as true or false. A carbon atom can
form up to four covalent bonds. True A carbon atom has six electrons in its outermost shell.
The bond between a carbon and hydrogen atom is a polar bond. Oxygen and nitrogen have a
stronger electronegativity than carbon (e.g., a strong pull on a shared electron). Bonds between
carbon and other atoms are relatively unstable and readily dissociate, resulting in the formation
of new molecules. The carbon backbone of a molecule is made up of a string of carbon atoms
held together with either single or double bonds. The carbon backbone of a molecule comes in a
variety of shapes: linear, ring-like, or highly branched. Carbon is a relatively large atom
allowing it to bind to more atoms than smaller atoms would, thereby making it more versatile.
Solution
Answer:
1. True, a carbon atom can form up to four covalent bonds as one carbon atom has four valence
electrons (in outermost shell). It is a fact that the number of valence electrons in a atom
determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used
to form four covalent bonds with various four atoms.
Example: CH4 (where one carbon atom share its outer valence electrons with up to four
hydrogens)
2. False, A carbon atom has four electrons in its outermost shell. As it has atomic number six,
means has total 6 electrons (two electrons in innermost shell and four in the outermost shell).
3. False, A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-
polar covalent bond are the bonds between two atoms which share equal number of electron(s)
with each other. Example: as in case of methane, where one carbon atom shares its 4 outer
valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number
of electron(s) with each other. Thus these bonds are partially ionic.
4. True, Oxygen and nitrogen have stronger electronegativity than carbon (e.g. a stronger pull on
a shared electron). Electronegativity is defined as the tendency of an atom to attract a shared
electron in a covalent bond towards itself. It is the result of the greater charge on the nucleus. In
periodic table, the electronegativity of the element increases as we move from left to right.
Nitrogen and Oxygen have greater charge on the nucleus as compared to the carbon thus, are
more electronegative than carbon.
5. False, Bonds between carbon and other atoms are relatively stable and not readily dissociate,
as the bonds between carbon and other atoms are relatively stable covalant bond which require
large amount of energy to break them.
6.True, The carbon backbone of a molecule is made up of a string of carbon atoms held together
with either single or double bonds. The Carbon atoms can share one, two or three electrons with
another Carbon.
A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

bonding in carbon compounds
1. 1.1 Explain the occurrence of carbon
compounds with straight chains,
branched chains and rings.
MODULE 1. THE CHEMISTRY OF
CARBON COMPOUNDS
Learning Outcomes
TOPIC: BONDING IN CARBON
COMPOUNDS
2. Carbon forms many more compounds than any
other element. This is partly because, once formed,
the carbon to carbon (C- C) single covalent bonds are
very strong in comparison to other single covalent
bonds.
It takes a lot of energy to break these strong bonds,
so the compounds form are stable.
The ability of carbon atoms to form chains or rings
compounds by joining together is called
CATENATION.
Carbon-carbon bonds are also non-polar, and this
helps to reduce their vulnerability by other
chemicals.
BONDING IN CARBON COMPOUNDS
3. Carbon atom:
is tetravalenttetravalent
has the ability to bond with other carbon atoms
to form straight chains, branches and ring
compounds. This is known as catenation.catenation.
has the ability to mix and rearrange the four
orbitals in the outer shell (hybridizationhybridization) e.g. sp3
,
sp2
, sp.
has resonance (delocalized electrons)
WHY CARBON IS THE UNIQUE THAT ITWHY CARBON IS THE UNIQUE THAT IT
FORMS A LARGE VARIETY OF COMPOUNDS?FORMS A LARGE VARIETY OF COMPOUNDS?
4. Carbon atoms are able to form a few types of
covalent bondscovalent bonds with other carbon atoms or atoms
of other elements:
Single bonds: C-C, C-H, C-O, C-X
(X = halogens)
Double bonds: C=C, C=O
Triple bonds: C C, C N≡ ≡
Organic compounds can be classified as
unbranched, branched or ring compounds.
5. Straight-chain molecules
that are unbranched may
contain single, double or
triple bonds. E.g.:
Straight (unbranched) Chain Compounds
Single bond Double bonds
Triple bonds
Branched- Chain Compounds
Branched chain
compounds consist of one
or more carbons of a
straight chain compound
forming bonds with more
than two carbons.
7. There are five types of formulae which can be
used to describe and identify organic
compounds:
Hybridisation in Carbon Compounds
Carbon is in Group IV of the Periodic Table. This
means that it has 4 electrons in its outer principle
quantum shell., which are able to form bonds with
other atoms. It exhibits TETRAVALENCY.
8. A covalent bond is formed by sharing of two
electrons, one from each atom. Carbon can form
four bonds because one of the 2s electrons in the
carbon atom is transferred to a 2p orbital to give
the four unpaired electrons necessary for forming
four bonds.
The process of mixing atomic orbitals is called
HYBRIDIZATION
Hybridisation in Carbon Compounds
11. Resonance
In ethane and ethene the electrons are localised.
In some substances, the molecular orbitals extend
over three or more atoms, allowing the electrons
free movement over these atoms. These electrons
are said to be delocalised.
Benzene (C6H6) has 6 carbon atoms arranged in a
ring. The bonds between the carbon atoms are
neither double nor single bonds. They are
somewhere in between. Making up a composite
structure from several different structures is called
mesomerism. The composite structure is called a
resonance hybrid.
12. Resonance
Resonance arises whenever we can write two or more
structures for a molecule with different arrangements
of the electrons but identical arrangements of atoms.
When resonance is possible, the substance that is a
resonance is said to have a structure that is a
resonance hybrid of the various contributing
structures.
13. Resonance in Benzene
Compounds such as benzene, which have this
delocalised electron ring structure are called aryl
compounds.
14. Key Points
A large number of carbon compounds are formed by
catenation- the joining of carbon atoms together to
form straight or branched chains of atoms or ring
compounds.
Most organic compounds are stable because of the
high value of the C-C bond energy and the non-polar
nature of this bond.
Hybridisation of s and p orbitals results in the
formation of an orbital with mixed character.
Resonance is where the structure of a compound is a
single form which is “in-between” two or more
structures.
