Question

Benzoic acid gives benzene on being heated with X and phenol gives benzene on being heated with Y. Therefore X and Y are respectively
(a) Soda-lime and copper
(b) Zn dust and NaOH
(c) Zn dust and soda-lime
(d) Soda-lime and zinc dust

Answer 1

Zn dust and sodium Line

Answer 2

Answer:

X and Y are soda-lime and zinc dust respectively.

Explanation:

The correct option is d) soda-lime and zinc dust because

Benzoic acid reacts with soda lime to give benzene.

C₆H₅COOH + Soda-lime → C₆H₆

Phenol on reaction with zinc dust forms benzene.

C₆H₅OH+Zn→C₆H₆

Therefore, Benzoic acid gives benzene on being heated with soda-lime and phenol gives benzene on being heated with zinc dust.

Thus, X and Y are soda-lime and zinc dust respectively.
