Which of the following will not produce the benzyl amine?

A)  \[\text{Benzamide}\xrightarrow{LiAl{{H}_{4}}}\]       

B)  \[\text{Phenyl nitrile}\xrightarrow{LiAl{{H}_{4}}}\]

C)  \[\text{2}-\text{phenyl ethyl isonitrile}\xrightarrow{LiAl{{H}_{4}}}\]

D)  \[~\text{2}-\text{phenyl ethoxamide}\xrightarrow{B{{r}_{2}}+KOH}\]

Correct Answer: C

Solution :

 Idea This problem includes conceptual mixing of nomenclature and reduction of acid amide and various important methods of preparation of amine. To solve this type of problem students are advised to complete the all given reactions and analyse the product obtained then to choose the correct option. [a] [b] [c] [d] Last process is a good example of Hoffmann bromide reaction in which carboxyl amide are converted into amine having one carbon atom less than carboxyl amide. TEST Edge Generally, in JEE Main these types of questions are asked so students are recommended to understand the preparation as well as properties of amine question based on property of amine may also be asked.
