Assertion : Boiling point of acid chlorides are lower than corresponding acids. Reason : Acetyl chloride can be prepared from acid by the action of \(\mathrm{PCl}_{3}\) or \(\mathrm{PCl}_{5}\).
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:
Acetaldehyde can be prepared by treating the acetic acid with phosphorus trichloride \(\left(\mathrm{PCl}_{3}\right)\), Phosphorus pentachloride \(\left(\mathrm{PCl}_{5}\right)\) and thionyl chloride \(\left(\mathrm{SOCl}_{2}\right)\). Acid chlorides have lower boiling points than corresponding carboxylic acids due to the absence of hydrogen bonding in their molecular structure. So the option (2) is correct.
