The reagents (A), (B), and (C) are:
a)b)c)d)
The reagents (A), (B), and (C) are:
a)b)c)d)
(d)
( ) can reduce both bond and ( ) group, but ( ) is more reactive than ( ) towards the reduction, so with 1 mol of ( ), only ( ) bond is reduced to ( ) bond. While ( ) or ( + Raney Ni) in excess reduce both( ) bond to ( ) bond and group to group, reduces only group to group, but does not reduce ( ) bond. So the answer is (d)
