A

`(I)lt(II)lt(III)lt(IV)`

B

`(I)gt(II)gt(III)gt(IV)`

C

`(III)lt(II)lt(I)lt(IV)`

D

`(II)lt(III)lt(IV)lt(I).`

Text Solution

Verified by Experts

The correct Answer is:
C
Dehydration of alcohols to conjugation. Greater is the scope of conjugation, more is the ease of dehydration.
The scope of conjugation is least in (II) followed by (II) and then (I). The scope of conjugation is maximum in (IV) i.e., it will be maximum dehydrated therefore, (c) is the correct sequence.
