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


Suggestion: You need more practice on problems based on Trends in Sizes, particularly of

Isoelectronic Ions.

Question number: 64


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.

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.

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


Suggestion: You need better understanding of chemical compounds used in medicines.

20

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.
