Select the correct option based on statements below:
| Assertion (A): | Compounds containing —CHO group are easily oxidised to corresponding carboxylic acids. |
| Reason (R): | Carboxylic acids can be reduced to alcohol by treatment with LiAlH4. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | (A) is false but (R) is true. |
Compounds containing the —CHO group are easily oxidized to corresponding carboxylic acids. It is due to the electron-withdrawing nature of the C =O group, the C —H bond in aldehydes is weak and easily oxidised to the corresponding carboxylic acids even with mild oxidizing agents like Fehling's solution and Tollen's reagents.
LiAlH4 is a strong reducing agent and reduced carboxylic acid to alcohol.
Hence, Assertion and Reason both are correct statements but Reason is not the correct explanation of assertion.
