Question

8.
Benzene diazonium chloride can be converted into
phenyl hydrazine with
(1) LAIH
(2) SnCly/HCI
(3) NaBH
(4) Na/C HOH​

Answer 1

Answer:

Option B : SnCly/HCI

Explanation:

Benzene diazonium chloride can be converted into phenyl hydrazine with the help of SnCly/HCI

• i.e. When Benzene diazonium chloride reacts with SnCly with the presence of HCl, then phenyl hydrazine is formed.
• This reaction is a reduction reaction.

Reason :

• When benzene diazonium chloride is heated in the presence of HCl, it forms phenol and nitrogen gas as its products.
• Later, on further heating the ions of diazonium salt react with water and nitrogen gas gets evolved.
• In this reaction, SnCly/HCI acts as a catalyst.
• In this reaction, SnCly/HCI speeds up the rate of reaction and accuracy or the reaction.
• This reaction is mostly performed to get aldehydes as the product.
