• B. (A)$\to$ (ii) ,(B)$\to$ (iii), (C)$\to$ (iv), (D)$\to$ (i)
• C. (A)$\to$ (iii) ,(B)$\to$ (iv), (C)$\to$ (i), (D)$\to$ (ii)
• D. (A)$\to$ (iv) ,(B)$\to$ (iii), (C)$\to$ (ii), (D)$\to$ (i)

Answer 1

The correct option is B (A)$\to$ (ii) ,(B)$\to$ (iii), (C)$\to$ (iv), (D)$\to$ (i)

A. A reaction of phenol with alkyl chloride in the presence of anhydrous $AlC{l}_3$ to give ortho and para-substituted phenol is called Friedel craft alkylation reaction.

B. The reaction of phenol with chloroform in basic medium gives $CHO$ group at ortho position in a phenol called salicylaldehyde. The reaction is called Riemer-Tiemann reaction.

C. The reaction of phenol with carbon dioxide in basic medium gives COOH group at ortho position in a phenol called salicylic acid. The reaction is called Kolbe's reaction.

D. The reaction of salicylic acid with hot soda lime ($NaOH+CaO$) gives phenol. The reaction is called decarboxylation.

(A)- (ii) ,(B)- (iii), (C)- (iv), (D)- (i)

Hence, option B is correct.
