(a) Complete the following reaction :

(b) Which of the following reactions is not possible ?
(I)
(III) `CH_3 OH + PhOLi`
(IV) .

Explanation

(a)
(b) `(I)` is possible , since phenol is more acidic, it will form a salt.

`(II)` is not possible because benzoic acid is more acidic so it would remain as such.
`(III)` is not possible because phenol is more acidic than `CH_3 OH`, so it would remain as such.
`(IV)` is possible because salicylic acid `(S.A)` is more acidic than benzoic acid, so `S.A` would form salt.
