Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 1

The products of reaction of alcoholic silver nitrite with ethyl bromide are

Detailed Solution for Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 1

TIPS/Formulae : Silver nitrite, being a salt of nitrous acid, occurs in two tautomeric forms.

 ion from AgNO2 may exist in two tautomeric forms, –O – N = O (nitrite ion) forming alkyl nitrites, and   (nitro group) forming nitroalkanes.

2 C2H5Br + 2AgNO2 → C2H5NO2 + C2H5ONO + 2 AgBr

Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 3

When nitrobenzene is treated with Br2 in presence of FeBr 3, the major product formed is m-bromonitrobenzene.
Statements which are related to obtain the m-isomer are

Detailed Solution for Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 3

TIPS/Formulae : Nitro group decreases the electron density at the meta-position in comparison to ortho and para position due to –I and –M effects.

The above intermediate is a resonance hybrid of three structures, hence is more stable than the corresponding intermediate from ortho and paraattack

Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 5

p-Chloroaniline and anilinium hydrochloride can be distinguished by

Detailed Solution for Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 5

TIPS/Formulae : Anilinium hydrochloride has ionisable chlorine whereas chlorobenze has non ionizable chlorine. Thus anilium hydrochloride gives white precipitate of AgCl with AgNO3.


In chloroaniline, –Cl is directly attached to benzene ring, hence it is non-reactive.

Hydrogen bonding plays a central role in the following phenomena

Detailed Solution for Test: MCQs (One or More Correct Option): Compounds Containing Nitrogen | JEE Advanced - Question 10

In ice, water molecules are excessively H-bonded giving a cage-like structure which is lighter than water.
Primary amines are more basic than tertiary amine, because the protonated 1° amines are extensively H-bonded and hence more stable than the corresponding protonated 3° amines.

Acetic acid undergoes dimerisation in benzene.
