Answer 1

Carbonyl hydroxyl a Carbonate group. (option. E) 2) a boon. At V-position Caubon, hydroxyl group is Total Carbon=5 (2-hydroylpentanore acid) Copton-B) 404 20 0 0 0 Inducture of halogen us -I means, it will stabilize the negative charge of conjugate Base and down the Group, Inductive effect decreases Hence option D! Huoroacetc acid will experience the most effecture Inductive effect toward its conjugate Base. 4 Cudin amid Cydic amide This is known as lactum option- B.
