NEET Chemistry Chemical Reactions MCQ Question
Which of the following statements about the chemical reactions of alcohols and phenols is correct?
Phenols undergo electrophilic substitution reactions more readily than alcohols due to the activating effect of the –OH group.
Primary alcohols are more easily dehydrated than tertiary alcohols under similar conditions.
The acidity of ortho methoxyphenol is greater than that of ortho nitrophenol.
Alcohols do not exhibit hydrogen bonding, making their boiling points lower than those of ethers.
Correct Answer
Detailed Explanation
The –OH group in phenols activates the benzene ring towards electrophilic substitution, directing incoming groups to the ortho and para positions due to resonance effects. This makes phenols more reactive compared to alcohols, which do not have such resonance stabilization.
