A statement of Assertion is given followed by a corresponding statement of Reason (R). Choose the correct answer from the given options.

Assertion: Compounds containing –CHO group are easily oxidised to corresponding carboxylic acids.

Reason: Carboxylic acids can be reduced to alcohols by treatment with LiAlH₄.

Both Assertion and Reason are correct and Reason is not the correct explanation of Assertion.

The correct answer is option 2. Both Assertion and Reason are correct and Reason is not the correct explanation of Assertion.

Assertion: Compounds containing \(–CHO\) group are easily oxidized to corresponding carboxylic acids.

The statement is correct. The \(–CHO\) group refers to an aldehyde functional group. Aldehydes are known to be easily oxidized to carboxylic acids. This happens because the aldehyde group \((–CHO)\) contains a hydrogen atom attached to the carbonyl carbon, which makes it highly susceptible to oxidation. Common oxidizing agents that facilitate this transformation include potassium permanganate \((KMnO_4)\), potassium dichromate \((K_2Cr_2O_7)\), and even oxygen in the air under certain conditions.

Reason: Carboxylic acids can be reduced to alcohols by treatment with \(LiAlH_4\).

The statement is correct. Lithium aluminium hydride \((LiAlH_4)\) is a strong reducing agent that can reduce carboxylic acids to primary alcohols. This reaction involves the conversion of the carboxyl group \((–COOH)\) to the hydroxyl group \((–OH)\) through the addition of hydrogen atoms.

Relationship Between Assertion and Reason: The oxidation of aldehydes to carboxylic acids and the reduction of carboxylic acids to alcohols are indeed both true statements. However, the ability of carboxylic acids to be reduced to alcohols by \(LiAlH_4\) does not explain why aldehydes are easily oxidized to carboxylic acids. 

The oxidation of aldehydes to carboxylic acids is due to the presence of a reactive hydrogen atom in the aldehyde group, which makes it susceptible to oxidation by oxidizing agents. The reduction of carboxylic acids to alcohols by \(LiAlH_4\) is a separate chemical process that does not provide an explanation for the ease of oxidation of aldehydes.

Both statements are individually correct, but the Reason does not explain the Assertion. Hence, the correct answer is: Both Assertion and Reason are correct and Reason is not the correct explanation of Assertion.
