Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond. Common alkenes include ethene, propene, but-1-ene, and but-2-ene, which have general formulas of C2H4, C3H6, C4H8, and C4H8 respectively. Alkene molecules are planar and exist as gases, being insoluble in water but soluble in non-polar solvents like cyclohexane. They are used to make plastics through polymerization and ethene is used to produce ethanol.

7.1 tetrahedral carbon alcohols 7.1
This document summarizes information about alcohols including their classification, physical properties, and uses. It lists common alcohols like methanol, ethanol, propan-1-ol, and butan-1-ol. Alcohols are classified as primary, secondary, or tertiary based on the number of carbon atoms attached to the hydroxyl group. Their physical properties make them generally soluble in water but less so in nonpolar solvents like cyclohexane. Common uses include producing alcoholic drinks through fermentation and as fuels when mixed with gasoline.
7.2 planar carbon esters 7.2
Esters are formed from the reaction of carboxylic acids and alcohols, with the loss of a water molecule. Their names are derived from the parent alcohol and acid, with the endings changed to -yl and -oate respectively. Esters have physical properties between their precursor alcohols and acids, such as higher boiling points than alkanes but lower than alcohols. They are soluble in both water and non-polar solvents like cyclohexane. Esters occur naturally in fruits and flowers, responsible for flavors and scents, and as fats and oils. Ethyl ethanoate is used as a solvent for printing inks and paints.
7.2 planar carbon carboxylic acids 7.2
This document discusses four carboxylic acids: methanoic, ethanoic, propanoic, and butanoic acid. It notes that methanoic and ethanoic acids are liquids while propanoic and butanoic acids are solids. Carboxylic acids are soluble in water and non-polar solvents due to their polar COOH groups. Carboxylic acids have higher boiling points than alcohols because they form dimers held together by hydrogen bonds between their C=O and O-H groups.
7.2 planar carbon aldehydes 7.2
This document discusses four common aldehydes - methanal, ethanal, propanal, and butanal. It notes that while aldehydes are liquids, methanal is a gas at room temperature. Aldehydes have higher boiling points than alkanes but lower than alcohols due to their polar carbonyl group. Short chain aldehydes are soluble in water because of this polar group, but solubility in water decreases with longer carbon chains while solubility in cyclohexane increases. The document also mentions benzaldehyde, an aromatic aldehyde found in almond kernels.
7.2 planar carbon ketones 7.2
Ketones like propanone and butanone are liquids at room temperature that have higher boiling points than alkanes due to their polar carbonyl groups, but lower than corresponding alcohols. These short chain ketones are soluble in water and non-polar solvents due to their polar carbonyl groups. Propanone is commonly used as a solvent, such as in nail varnish remover, due to its solvent properties.
7.1 tetrahedral carbon alkanes 7.1 (1)

It concludes that alkanes are used as fuels in mixtures like petrol, diesel, LPG and natural gas.
Alcohol ppt slides
Alcohols belong to a homologous series of organic compounds similar to alkanes and alkenes, with the general formula CnH2n+1OH. Methanol has one carbon atom, ethanol has two, and propanol has three. Alcohols are named by replacing the ending of the parent alkane with "ol". Alcohols are soluble in water and can undergo combustion, oxidation, and fermentation reactions. Ethanol is produced industrially by hydration of ethene or fermentation of carbohydrates by yeast. Alcohols have uses as solvents, in alcoholic drinks, and fuel.

Ethanal is also produced when ethanol is metabolized in the human body. Sodium dichromate(VI) can be used to prepare ethanal by refluxing an excess of ethanol with an acidified solution of the oxidizing agent. The ethanal is distilled off as it is formed to prevent further oxidation to ethanoic acid. Primary alcohols are oxidized to aldehydes which can be further oxidized to carboxylic acids.

7.2 bonding in benzene 7.2
Benzene has the molecular formula C6H6. Its ring structure was first deduced by Friedrich Kekulé in 1865, resolving a mystery about how the carbon atoms bond. Researchers later discovered through X-ray crystallography that the carbon-carbon bonds in benzene are all the same length, indicating resonance. This is due to six electrons being delocalized in a planar ring above and below the nuclei, allowing for stable overlapping orbits between carbon atoms.

Carboxylic acids are soluble in water and non-polar solvents due to their polar COOH groups. Carboxylic acids have higher boiling points than alcohols because they form dimers held together by hydrogen bonds between their C=O and O-H groups.

Students are expected to understand bonding, naming, drawing structures, accounting for properties and discussing industrial and other uses of these organic substances. They also carry out experiments such as preparing samples of ethene, ethanal and ethanoic acid.
7.3 reactions as acids
Alcohols react with sodium to form sodium salts and hydrogen gas. For example, ethanol reacts with sodium to form sodium ethoxide and hydrogen gas. Carboxylic acids are stronger acids than alcohols because their anions are more stable due to electron delocalization. Carboxylic acids react with metals like magnesium to form salts and hydrogen gas, with bases like sodium hydroxide to form salts and water, and with carbonates like sodium carbonate to form salts, water, and carbon dioxide.
6.2 factors affecting rates of reaction
The document discusses collision theory and factors that affect the rate of chemical reactions. It investigates how concentration, temperature, and particle size impact the rate through experiments. Increasing concentration increases collisions and reaction rate. Smaller particle size increases surface area and reaction rate. Higher temperatures provide more energy for collisions to overcome the activation energy, again increasing reaction rate. Ionic reactions tend to be faster than covalent reactions as ions can move freely in solution without bonds to break first.

Reading corner guidelines
This document provides guidelines for setting up a school library or reading corner, including recommendations for location, shelving, furniture, equipment, signage, managing the library collection, and cataloguing systems. The ideal location is at the heart of the school, is highly visible and accessible, and is well-lit with power and internet. Shelving options include wall-mounted and freestanding units of various types. Furniture should be durable and allow for both formal and informal seating. Collections should be tailored to student interests and abilities. Small libraries can use simple tracking systems while larger ones may implement software-based cataloguing of fiction and non-fiction sections.
