Question

37. a) Explain the mechanism of nitration of benzene. b) Write the Newman's projections of ethano.​

Answer 1

Answer:

A) - - - The mechanism for nitration of benzene:

Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion.

B) - - - - - In a Newman projection the carbon-carbon bond is viewed along its axis and the two carbon atoms are repesented by a circle. The bonds attached to the front carbon are represented by lines going to the centre of the circle, and bonds attached to the rear carbon are represented by lines going to the edge of the circle.
