Vedclass · Answer

(B) The dehydration of alcohols to alkenes requires specific conditions depending on the degree of substitution of the alcohol.Primary $(1^{\circ})$ alcohols,like butan$-1-$ol in option $(B)$,are the least reactive towards dehydration and typically require concentrated acid (e.g.,$95\% \ H_2SO_4$) and high temperatures (around $443 \ K$) to proceed.Option $(B)$ suggests the dehydration of a primary alcohol at a very low temperature $(300 \ K)$ with a lower concentration of acid $(75\% \ H_2SO_4)$,which is insufficient to drive the elimination reaction.Secondary and tertiary alcohols are more reactive and can undergo dehydration under milder conditions,making options $(C)$ and $(D)$ feasible.
