AIIMS 2014 Chemistry Alcohols Reaction MCQ Question
Assertion Reaction of alcohols with SOCl2 is catalysed by the presence of a tertiary amine (R3N). Reason Tertiary amine promote the reaction by reacting with the by-product HCl.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true and Reason is not the correct explanation of Assertion
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
The assertion is correct because the reaction of alcohols with SOCl2 (thionyl chloride) is indeed facilitated by tertiary amines, which act as catalysts. The reason is also true, as tertiary amines help to neutralize the hydrochloric acid (HCl) by-product formed during the reaction, thereby promoting the reaction's progress. Thus, the reason accurately explains why the assertion holds true, making option A the correct choice.
