Answer 1

Answer:

Ethyl cyanides gives an additional product having one or more carbon atoms with Grignard reagent, which is later on hydrolysis gives 1- phenyl propanone. R1 and R2 represent two different alkyl groups. This reaction is completed in two steps. In the first step the phenyl group of Grignard reagent acts as a nucleophile.♥️

Answer 2

Answer:

● Ethyl cyanide to 1-phenylpropanone -

Ethyl cyanide is treated with phenyl magnesium bromide to get 1-phenylpropanone.

CH3-CH2-CN + C6H5-MgBr --> CH3-CH2-C(NMgBr)-C6H5

CH3-CH2-C(NMgBr)-C6H5 + 3H2O --> CH3-CH2-CO-C6H5 + Mg(OH)2 + NH3 + HBr

# Extra information -

Compounds with general formula R-MgBr are called Grignard reagent.
