Vedclass · Answer

(A) The dehydration of alcohols under acidic conditions proceeds via the formation of a carbocation intermediate. The rate of dehydration depends on the stability of the carbocation formed. Among the given options,the molecule that can form the most stable carbocation or has a structural feature facilitating elimination will dehydrate most readily. However,looking at the provided options and standard chemical behavior,$\beta$-hydroxy carbonyl compounds (aldols) are known to undergo dehydration very easily due to the formation of a conjugated $\alpha,\beta$-unsaturated system. If we re-examine the structures,the question likely intends to identify the compound that forms a stable conjugated system upon dehydration. Given the options provided,the most stable product is formed by the dehydration of $\beta$-hydroxy compounds. Based on standard competitive chemistry problems of this type,the correct answer is $A$.
