(i) How will you convert nitrobenzene into
1) 1,3,5 - trinitrobenzene 2) o and p - nitrophenol
(ii) Differentiate between Globular and fibrous proteins.

Explanation

(i) 1. Conversion of nitrobenzene into 1,3,5 - trinitrobenzene:

2. Conversion of nitrobenzene into o and p- nitrophenol:
Nitrobenzene heated with solid KOH at 340 K gives a low yield of a mixture of O-and P-nitrophenols.

(ii) Difference between Globular and fibrous proteins.
