Question

Given below are two statements: Statement I: The boiling point of p-nitrophenol is higher than the o-nitrophenol. Statement II: Alcohols are less acidic than the Phenols.

• A. Both Statement I and Statement II are correct.
• B. Both Statement I and Statement II are incorrect.
• C. Statement I is correct but Statement II is incorrect.
• D. Statement I is incorrect but Statement II is correct.

Hint:

Para is stronger (boiling point) because it bonds with neighbors; ortho is weaker because it bonds with itself.

Answer 1

The Correct Option is A

Step 1: Concept
Boiling points depend on intermolecular forces; acidity depends on the stability of the conjugate base.

Step 2: Meaning
o-Nitrophenol has intramolecular hydrogen bonding, whereas p-nitrophenol has intermolecular hydrogen bonding. Intermolecular bonds require more energy to break, leading to a higher boiling point.

Step 3: Analysis
Phenols are more acidic than alcohols because the phenoxide ion is stabilized by resonance (delocalization of the negative charge into the benzene ring), which is not possible in simple alcohols.

Step 4: Conclusion
Both statements are scientifically accurate. Final Answer: (A)
