Question

What is INCORRECT about the product written in the below given reaction?

$$\mathrm{R}-\mathrm{CH}{\phantom{A}}_2-\mathrm{OH}\stackrel{\mathrm{PCC}}{\to }\mathrm{R}-\mathrm{COOH}$$

विकल्प

• The product should be R – CHO instead of R – COOH.

• The product should be R – CO – R instead of R – COOH.

• The product should be an aldehyde with one carbon atom more than the reactant alcohol.

• The product should be R – CH₃ instead of R – COOH.

Answer 1

The product should be R – CHO instead of R – COOH.

Explanation:

Pyridinium chlorochromate (PCC) is a weak oxidizer. lt converts primary alcohols to their aldehydes without converting them to carboxylic acids.
