CHXII12:ALDEHYDES KETONES AND CARBOXYLIC ACIDS

323797 Assertion :
Carboxylic acids are reduced to alkanes on reaction with $HI$ in presence of red phosphorus.
Reason :
Melting point of carboxylic acids shows a regular pattern.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

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

3 Assertion is correct but Reason is incorrect.

4 Assertion is incorrect but Reason is correct.

Explanation:

Carboxylic acids can be reduced to alkanes by reacting with $HI$ in the presence of red phosphorus. Initially this forms an acyl iodide $(RCOCl)$ and subsequently undergoes further reduction to yield an alkane with the removal of carbonyl oxygen and the generation of iodide ion $(I^{-})$ .
The overall reaction can be represented as:
$RCOCl + HI \to RH + ICl$
Melting point of carboxylic acids are not in a regular order. So the option (3) is correct.
