Assertion: Tert $4$ Butyl alcohol undergoes acid catalysed dehydration readily than propanol.
Reason: $3º$ Alcohols do not give Victor$-$Meyer's test.

A
Assertion and reason both are correct statements and reason is correct explanation for assertion.
✓
Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C
Assertion is correct statement but reason is wrong statement.
D
Assertion is wrong statement but reason is correct statement.

Answer

Correct option: B.

Assertion and reason both are correct statements but reason is not correct explanation for assertion.

Alcohol which forms the more stable carbocation undergoes dehydration more readily. Since tert$-$butyl alcohol forms more stable tert$-$butyl cation, therefore, it undergoes dehydration more readily than propanol.
