Question

*biphenyl on oxidation with chromic acid gives what*​

Answer 1

Answer:

It is a strong oxidant, and it oxidizes the alcohol as far as possible without breaking carbon-carbon bonds. Chromic acid oxidizes primary alcohols to carboxylic acids, and it oxidizes secondary alcohols to ketones. Tertiary alcohols do not react with chromic acid under mild conditions.

Answer 2

Chromic acid requires the reactant to be an alcohol for the oxidation to occur.

• Biphenyl is a combination of two benzene rings attached together.

• This compound lacks the presence of 'OH' group and therefore, oxidation will not occur.

• Chromic acid can oxidise primary alcohol, secondary alcohol, and aldehyde compounds.

• When chromic acid oxides primary alcohol, it gives carboxylic acid.

• When chromic acid oxides secondary alcohol, it gives ketones.

• When chromic acid oxides aldehydes, it gives carboxylic acid.
