उत्तर
(i) (a) and (e) both are nucleophiles.
(iii) In (c) carbon atom is sp2 hybridised.
Explanation:
HO− and Cl− are nucleophiles.
In (iii), C atom is sp2 hybridised due to formation of \[\ce{C - OH}\] bond and breaking of \[\ce{C - Cl}\] bond simultaneously. So, in the transition state, the C atom is bonded to only 3 H atoms completely.
