Question

Which of the following does not give yellow solid on treatment with sodium hypoiodlte?

Options

• Acetophenone

• Pentan-3-one

• Pentan-2-one

• Ethanal

Answer 1

Pentan-3-one

Explanation:

Pentan-3-one does not produce yellow solid when treated with sodium hypoiodite since only methyl ketones produce this reaction. Sodium hypoiodite oxidizes ketones with at least one methyl group attached to the carbonyl carbon atom to sodium salts of matching carboxylic acids. The iodoform reaction is the name for this reaction.
