NEET Chemistry Properties of Phenols MCQ Question
Which combinations of the following statements about the properties of phenols are correct? 1. Phenols are less stable than their corresponding phenoxide ions due to charge separation in resonance structures. 2. Phenol has a higher acidic strength compared to ethanol. 3. The reaction between phenols and acid chlorides occurs in the presence of a base to neutralize HCl. 4. The cleavage of the C–O bond occurs only in alcohols and not in phenols.
1, 2, and 3 are correct.
2, 3, and 4 are correct.
1, 3, and 4 are correct.
1, 2, 3, and 4 are correct.
Correct Answer
Detailed Explanation
Statement 1 is correct because phenols are less stable than phenoxide ions due to charge separation in resonance. Statement 2 is also correct as phenol is significantly more acidic than ethanol. Statement 3 is correct as well; phenols react with acid chlorides in the presence of a base to neutralize HCl. Statement 4 is incorrect because phenols can undergo C–O bond cleavage under certain conditions.
