Product stability

Vedclass · Answer

(B) The reactivity of alcohols towards acidic dehydration depends on the stability of the alkene formed (Product stability).In the first case,the product $Ph-CH=CH-CH_3$ is resonance-stabilized due to conjugation with the phenyl ring,making it much more stable than the product $CH_3-CH=CH-CH_3$ formed from the second alcohol.Higher product stability leads to higher reactivity of the starting alcohol.

Reactivity of given alcohols for acidic dehydration can be explained by $Ph-CH_2-CH(OH)-CH_3 > CH_3-CH_2-CH(OH)-CH_3$:
