1.	Consider the following sequence of reactions `C_(6)H_(5)CH_(2)Ioverset(KCH)rarrA overset(H_(2)//Ni)rarrB` the final product `(B)` is .A. `C_(6)H_(5)CH_(2)CH_(2)NH_(2)`B. `C_(6)H_(5)CH_(2)NH_(2)`C. `C_(6)H_(5)NH_(2)`D. `C_(6)H_(5)NHCH_(3)`
Answer» Correct Answer - A On treatment with potassium or sodium cyanide alky1 halides undergo nucleophilic substitution of form alky1 nitriles which on reduction with `LiAIH_(4)(LAH)` or catalytic hydrogenation form primary amines which have one carbon more than the alky1 halide used `C_(6)H_(5)CH_(2)Br overset(KCN)rarrC_(6)H_(5)CH_(2)CHoverset(H_(2)//Ni)rarrC_(6)H_(5)CH_(2)CH_(2)NH_(2)` This reaction is used for ascent of series .
