Question

Which of the following is not a use of formaldehyde?

(a) Preservation of biological specimens

(b) Manufacturing of bakelite

(c) Silvering of mirrors

(d) Preparation of acetic acid.

This question was addressed to me by my college professor while I was bunking the class.

Asked question is from Uses of Aldehydes and Ketones in section Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12

Answer 1

Right choice is (d) Preparation of acetic acid.

For explanation I would say: Formaldehyde consists of only a single carbon atom and cannot be used as a starting compound for the preparation of acetic acid. However, it is used in the manufacture of bakelite, glues and polymeric products. It also acts as a reducing agent in the silvering of mirrors.
