1 / -0

Which is dehydrated to a maximum extent using conc.$$ H_2 SO_4 $$?

A

B

C

D

Solution

Extent of dehydration using conc. $$\mathrm{H_2SO_4}$$ depends upon the stability of intermediate carbonium ion formed in the reaction.
Among the given options, Intermediate carbonium ion formed in the above reaction has highest stability.

Hence, Option "D" is the correct answer.
