(b)
Interpretation:
The given multistep synthesis by using necessary reagents is to be shown.
Concept introduction:
The starting material for the given synthesis is a bicyclic
(c)
Interpretation:
The given multistep synthesis by using necessary reagents is to be shown.
Concept introduction:
In the given synthesis the starting material is biphenyl compound. In the compound of biphenyl two benzene rings are attached with each other by the carbon-carbon bond and with the loss of two hydrogen atoms. Biphenyl first undergoes nitration with nitric acid and sulphuric acid. Then it undergoes reduction for nitro group to amine group. Biphenyl amine reacts with ethyl chloride and converts to ethylbiphenyl amine. On further reduction and reaction with suitable reagent desired product is formed.
