Epichlorohydrin is

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 1
SRMJEEE Chemistry Mock Test - 1 - Question 2

Acetaldehyde and acetone differ in their reaction with

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 2


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.

SRMJEEE Chemistry Mock Test - 1 - Question 5

A triglyceride can have how many different acyl groups?

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 5
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.

SRMJEEE Chemistry Mock Test - 1 - Question 12

Which relation is correct ?

SRMJEEE Chemistry Mock Test - 1 - Question 13

Chemical equilibrium is dynamic in nature, because

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 13

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

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 19
SRMJEEE Chemistry Mock Test - 1 - Question 20

The value of gas constant per degree per mole is approximately

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 20
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
SRMJEEE Chemistry Mock Test - 1 - Question 21

SRMJEEE Chemistry Mock Test - 1 - 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

Detailed Solution for SRMJEEE Chemistry Mock Test - 1 - Question 29

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
