Question

Which of the following statements is not correct? (A) Replacement of halogen by - NH 2 in alkyl halide is a nucleophilic substitution reaction. (B) Aryl halides show more reactivity as compared to alkyl halides in the replacements of halogen by the - NH 2 group. (C) During the replacement of halogen by - NH 2 group, ammonia is taken in large excess so as to avoid the formation of 2° and 3° amines. (D) Tertiary alkyl halide generally produces alkene instead of the replacement of halogen by - NH 2 group.

Correct answer is (b) Aryl halides show more reactivity as compared to alkyl halides in the replacements of halogen by the - NH 2 group.

Q. Which of the following statements is not correct?

Replacement of halogen by $- N H_{2}$ in alkyl halide is a nucleophilic substitution reaction.

Aryl halides show more reactivity as compared to alkyl halides in the replacements of halogen by the $- N H_{2}$ group.

During the replacement of halogen by $- N H_{2}$ group, ammonia is taken in large excess so as to avoid the formation of $2^{\circ}$ and $3^{\circ}$ amines.

Tertiary alkyl halide generally produces alkene instead of the replacement of halogen by $- N H_{2}$ group.

Correct answer is (b) Aryl halides show more reactivity as compared to alkyl halides in the replacements of halogen by the $- N H_{2}$ group.
