      Thanks Princy for your comments... In Q 31 the first step is Dehydrohalogentaion process lead to the formation of ethene, then Bromine will add up on ethene by halogenation process and after all in last step bromine will be replaced by CN via SN2 reaction leads to formation of the product (B)

      Walden inversion is stereo chemical inversion of product relative to reactant stereo configuration means if reactant is chiral and d/l form than the product will be l/d (Invered)form... It is the characteristic property shown in SN2 reactions. :)
