InterviewSolution

1.	The reaction`CH_(3)I+NH_(3)(excess)underset(2.OHbar)overset(1.heat)rarrCH_(3)NH_(2)+HI` is an example of aA. unimolecular nucleophilic substitution reactionB. bimolecular nucleophilic substitution reaction .C. unimolecular eletrphilic substitution reactionD. bimolecular electrophilic substitution reaction .
Answer» Correct Answer - B When an alky1 halide is heated with excess of ammonia it undergoes bimolecular `(S_(N)2)` nucleophilic substitution and the ammonium salt formed initially on basification gives a primary amine `CH_(3)INH_(3)(excess)overset(heat)rarrCH_(3)overset(+)(NH_(3))Ioverset(OHbar)rarrCH_(3)NH_(2)` .
