NEET Chemistry Chemical Reactions MCQ Question
Which of the following statements correctly describe the reactions of phenols and alcohols?
Phenol is more acidic than ethanol due to resonance stabilization of its conjugate base.
Primary alcohols are dehydrated more easily than tertiary alcohols under mild conditions.
Electrophilic substitution in phenols occurs predominantly at the meta position.
Alcohols can be oxidized to form carbon-oxygen double bonds, losing hydrogen atoms in the process.
Correct Answer
Detailed Explanation
Phenol is indeed more acidic than ethanol because the negative charge on the conjugate base is stabilized by resonance. Alcohols, particularly tertiary ones, are dehydrated more readily than primary ones, contrary to option B. The electrophilic substitution in phenols predominantly occurs at ortho and para positions, not meta, making option C incorrect. Alcohols do undergo oxidation to form carbon-oxygen double bonds as mentioned.
