QUESTION: 1

Epichlorohydrin is

Solution:
QUESTION: 2

Acetaldehyde and acetone differ in their reaction with

Solution:


As methyl group donates electrons, hydrogen atom withdraws electrons; this makes the molecule more polarized, and it makes the molecule more reactive. Compared to acetone, acetaldehyde has less stearic effects, and other molecules can approach easily. Due to these reasons, acetaldehyde is more reactive than acetone.

QUESTION: 3

Among the following hydrocarbons which decolourise bromine water, but does not give precipitate with ammonical AgNO3 is

Solution:
QUESTION: 4

A triglyceride can have how many different acyl groups?

Solution: Esterification of glycerol will produce TG or PL. Glycerol with one acyl group is a monoacylglycerol (MAG), those with 2 acyl groups a diacylglycerol (DAG) and of course those with 3 a triacylglycerol or triglyceride molecule. There are very specific enzymes involved in each of the three esterification steps.
QUESTION: 5

Which of the following does not react with AgCl?

Solution: AgCl is insoluble in water and NaNO3 is soluble in water.and also the reverse reaction of the reaction u asked is highly stable and unidirectional.

Solution:
QUESTION: 10

Pi-bonds do not alter the shape, but merely shorten the

Solution:

A carbon-carbon double bond consists of one sigma bond and one pi bond. This double bond is stronger than a single covalent bond (599 kJ/mol for C = C vs. 348 kJ/mol for C—C) and also shorter with an average bond length of 1.33 Angstroms (133 pm).

QUESTION: 11

Which of the following is the strongest acid?

Solution:
QUESTION: 12

Which relation is correct ?

Solution:
QUESTION: 13

Chemical equilibrium is dynamic in nature, because

Solution:

The two opposite processes, forward reaction and reverse reaction, keep on occurring in it all the time but at exactly equal rates (or equal speeds)
A chemical reaction does not stop after reaching the equilibrium state, only the rate of the forward and the reverse reactions become equal at the equilibrium state

QUESTION: 14

Solution:

The total number of isomers, including the stereo-isomers, with formula C4H7Cl is 12. Out of this, 3 are cyclic and the remaining are acyclic.

 

QUESTION: 18

The charge required to liberate 112 ml of hydrogen from acidified water is

Solution:
QUESTION: 19

Which of the following ions are paramagnetic in character?

Solution:

Ni2+ is paramagnetic in nature as it has unpaired electrons.

QUESTION: 20

The value of gas constant per degree per mole is approximately

Solution: The value of gas constant per degree per mol is approximately 2 cal.

Note: 
 In the equation of state of an ideal gas Pv=nRT the value of universal gas constant would depend only on the units of measurement. It is independent of the nature of the gas, the pressure of the gas and the temperature of the gas.

For example:-R=8.314J/mol k

R=1.99 cal/mol /k
QUESTION: 21

When ammonium chloride is added to ammonia solution , the pH of the resulting solution will be

Solution: Ammonium chloride is a strong acid...ammonium hydroxide(solution) is weak base. So when ammonium chloride is added to ammonium solution,the pH of the solution goes from higher number to lower number..that is it decreases
QUESTION: 22

Solution:
QUESTION: 29

If 0.183 of an aromatic monobasic acid requires 15ml of N/10 sodium hydroxide for complete neutralisation, then molecular weight of the acid is

Solution:

Milliequivalents of NaOH = 15×1/10 = 1.5 = 0.0015 equivalents
For neutralization equivalents of acid = 0.0015
As the acid is monobasic, n factor= 1, so moles of acid required = 0.0015/1 = 0.0015
weight/MW = 0.183g/0.0015 MW
MW= 122g

QUESTION: 30

What is oxidation number of Fe in Fe(CO)₅?

Solution: CO group is neutral. It has no charge due to this the charge on Fe is also zero.

Solution:
QUESTION: 32

If 20 ml of 0.4 N NaOH solution completely neutralises 40 ml of a dibasic acid, the molarity of the acid solution is

Solution:


QUESTION: 33
