Vedclass · Answer

(B) The dehydration of alcohols proceeds via the formation of a carbocation intermediate. The ease of dehydration depends on the stability of the carbocation formed after the loss of the water molecule.$1$. Compound $III$ forms a conjugated carbocation (allylic and conjugated with the other double bond),which is the most stable.$2$. Compound $II$ forms an allylic carbocation,which is more stable than the simple secondary carbocation formed from $I$.$3$. Compound $I$ forms a simple secondary carbocation.Thus,the stability order of the carbocations is $III > II > I$,which is also the order of ease of dehydration. Therefore,the correct order is $III > II > I$.

The correct order of ease of dehydration of the following compounds is:
