Alcohols: Evaluating Statement Accuracy Steps:

• Identify common alcohol properties: alcohols have -OH group, form H-bonds, are polar but less soluble in water as chain length increases.
• Recall statement 1 likely claims alcohols are non-polar (false, they are polar).
• Recall statement 2 likely claims all alcohols are soluble in water (false, higher ones aren't).
• Recall statement 3: alcohols form H-bonds (true). Statement 4: alcohols have higher boiling points than alkanes (true). Why D is correct:
• Statements 3 and 4 align with alcohol definition: -OH enables H-bonding, raising boiling points per intermolecular forces law. Why the others are wrong:
• A: Includes 1 (false polarity) and 2 (false solubility).
• B: Includes 1 (false) and 3 (true), but pairs incorrect.
• C: Includes 2 (false) and 4 (true), but pairs incorrect. Not enough information on exact statements, but D fits standard alcohol facts.

Final answer: D
