Answer 1

answer - benzene diazonium chloride on boiling with dilute sulphuric acid gives phenol.

Answer 2

Benzene diazonium chloride on boiling with dilute sulphuric acid gives

(a) Toluene

(b) Benzoic acid

(c) Benzene

(d) Phenol ✔

Explaination :-

Benzene diazonium chloride on boiling with dilute sulphuric acid gives phenol, nitrogen gas and Hydrochloric acid.

Chemical equation :-

$\mathsf{C_{6}H_{5}N_{2} {}^{ + } Cl {}^{ - } + H_{2}O \longrightarrow C_{6}H_{5}OH + N_{2} \uparrow + HCl}$

Additional information :-

Colour and odour :-

• Pure amine are colourless but develops colour on keeping in air or on storage due to atmospheric oxidation.

Solubility :-

• Lower aliphatic amine can form hydrogen bonds with water molecules and hence are soluble in water.

Boiling point :-

• Amine are Polar and hence form intermolecular H-bonds and therefore, they have higher boiling point.
