1. Introduction
iON PrepTest helps you achieve your targets as per below stated objectives:
 Improve your conceptual understanding
 Address specific areas of improvement personalized to you
 Prepare you to crack any competitive Examination
TCS iON PrepTest is designed to improve the conceptual clarity of your subjects. The
analysis report provides you a detailed view of your performance and equips you to crack
any Examination that comes your way. Analytics on various parameters gives you deeper
understanding of your performance at individual and national level. Also, the report helps
you in realize your areas of improvement and guides you to focus on them.
Post analysis, practice material specific to the errors you have committed will be provided to
you. We recommend you to make use of the practice material to overcome your mistakes in
future.
Post error practice, you need to take an improvement Examination which will help you
gauge your improvement over base Examination and will take your preparation to the next
level. You will get closer to your learning and career targets.
We once again recommend you to make use of the analysis and practice material to achieve
your goal.

4.4 Error Analysis: Chemistry
This section analyzes each error you have made and what could be the potential reason for
your mistake. It also provides suggestions on how do you overcome such errors in future.
Practice material for each error is provided to you to minimize the errors in future and
improve your score.
Question number: 62
Explanation: You may have applied the concept incorrectly.
Suggestion: You need more practice on problems based on Trends in Sizes, particularly of
Isoelectronic Ions.
Question number: 64
Explanation: You may have applied the concept incorrectly.
Suggestion: You need better understanding of the concept Crystal Field Theory and
splitting of d-orbitals in square planar, octahedral and tetrahedral fields.
Question number: 67
Explanation: You got this answer because you have considered the heat of hydrogenation
is proportional to stability of alkene. Since it is most stable, you got maximum heat of
hydrogenation in this case.
Suggestion: Heat of hydrogenation is inversely proportional to stability of alkene.

19. 18
Question number: 69
Explanation: You got this answer because you have considered that bromide group is more
electron withdrawing than acetyl group.
Suggestion: Acetyl group withdraws electrons through resonance effect, so it is more
dominating. Bromide withdraws electrons through inductive effect only.
Question number: 71
Explanation: You got this answer due to incorrect calculation.
Suggestion: Focus on calculations when you attempt such questions.
Question number: 75
Explanation: You got this answer because you have considered that ammonia is a strong
base, so complete neutralization at equivalence point will give neutral solution
Suggestion: Ammonia is not a strong base, so the salt formed at equivalence point will
hydrolyze and will produce acidic solution.
Question number: 77
Explanation: You got this answer because you have considered that oxidized agent acts as
oxidizing agent.
Suggestion: Oxidized reactant works as a reducing agent and reduced reactant works as
oxidizing agent.
Question number: 78
Explanation: You got this answer because you have considered that and comes in
contact with each other at face diagonal for which rubidium ion becomes =
Suggestion: In rock salt structure, cations and anions come in contact with each other at
the edges of unit cell.

20. 19
Question number: 79
Explanation: You got this answer because you have considered that the vapor pressure of
heptane is very low, so you neglect it and considered the solution of non-volatile
component.
Suggestion: We cannot neglect the vapor pressure of heptane. Since its vapor pressure will
always contribute to the vapor pressure of the solution.
Question number: 80
Explanation: You got this answer because you have taken molecular weight as 173.21 g,
which is the molar mass, that is, mass of molecules.
Number of C atoms
Mass of 1 molecule = g
Suggestion: In the question, it is clearly asked to calculate carbon atoms in one molecule,
so we need mass of one molecule. Mass of one molecule can be obtained directly from
molecular weight but in atomic mass units. These need to be converted into grams before
calculate the number of carbon atoms.
Molecular weight ⇒ Mass of 1 molecule relative to 1 u
⇒ Mass of 1 molecule = 173.21u
⇒ Mass of 1 molecule = g
Question number: 83
Explanation: You got his answer because you performed wrong calculations of entropy and
enthalpy.
Suggestion: The change is free energy depends on enthalpy as well as entropy, so it
should be calculated correctly.
Question number: 84
Explanation: You may have applied the concept incorrectly.
Suggestion: You need better understanding of chemical compounds used in medicines.

Question number: 85
Explanation: You got this answer because you have considered ring II as more active, so
Br gets added as Para positive w.r.t –Ar and meta w.r.t –CONHAr.
Suggestion: The group –CONHAR moderately deactivates the benzene ring, so ring II is
relatively less reactive.
Question number: 86
Explanation: You got this answer because you have considered that substitution of one
hydrogen atom at all positions will produce a product and also included stereoisomers.
Suggestion: Substitution at all positions will not produce constitutional isomers.
At the beginning of the carbon chain, three identical methyl groups are present
and at the end of the chain, two identical methyl groups are present. So, only two
structural isomers are formed out of five different positions.
Question number: 87
Explanation: You got this answer because you have considered that entropy is always the
dominating factor to decide the structure of molecule.
Suggestion: In fibers, cross-linking through strong intermolecular forces exists which
indicates regular pattern of fibers. This implies that randomness is suppressed in fibers, so
the stability of structure is determined by enthalpy.
