Question

Assertion Reaction of alcohols with $SOCl _{2}$ is catalysed by the presence of a tertiary amine $\left(R_{3} N \right)$.
Reason Tertiary amine promote the reaction by reacting with the by-product $HCl$.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true and Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Both Assertion and Reason are false

Answer 1

Answer: (A)

$ROH + SOCl _{2} \longrightarrow R- Cl + SO _{2}+ HCl $
$HCl +R_{3} N \longrightarrow R_{3} N \cdot HCl$
