In the following question a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion: Compounds containing \text {-CHO} group are easily oxidised to corresponding carboxylic acids.

Reason: Carboxylic acids can be reduced to alcohols by treatment with \text {LiAlH}_{4}

(i) Assertion and reason both are correct and the reason is the correct explanation of assertion.

(ii) Assertion and reason both are wrong statements.

(iii) The assertion is a correct statement but the reason is the wrong statement.

(iv) The assertion is a wrong statement but the reason is the correct statement.

(v) Assertion and reason both are correct statements but the reason is not the correct

explanation of assertion

Answers (1)

The answer is the option (v). Due to high electronegativity of oxygen, carbonyl group in aldehydes are a strong electron-withdrawing group. This weakens the C-H bond in aldehydes. Even a weak oxidizing agent can oxidize the aldehydes into the corresponding carboxylic acids.
