Benzyl amine may be alkylated as shown in the following equation : C_6H_5 CH_2NH_2 + R - X to C_6H_5CH_2NHR Which of the following alkyl halides is best suited for this reaction through S_(N^1) mechanism ?

Answer»

`CH_3 BR`
`C_6 B_5 Br`
`C_6 H_5 CH_2 Br`
`C_2 H_5 Br`

Solution :`C_6 H_5 CH_2Br` is best suited for `S_(N^1)` REACTION because upon IONIZATION its gives the resonance STABILIZED benzyl carbocation
` (C_6 H_5 CH_(2)^(+))`
