If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Vedclass · Answer

(A) The given order of dehydration is correct due to the following reasons:$(i)$ Alcohols that lead to the formation of conjugated alkenes are dehydrated more readily because the resulting product is more stable.$(ii)$ $2-Cyclohexenol$ is dehydrated more easily than $3-cyclohexenol$ because the carbocation formed from the former is stabilized by resonance with the double bond (allylic carbocation),making it more stable than the carbocation from the latter.$(iii)$ Phenol is not dehydrated under standard conditions due to the high stability of the $C-O$ bond resulting from resonance,which gives it partial double-bond character.
