For the given reaction , which alcohol will be most reactive?
1 \(\mathrm{CH}_{3} \mathrm{OH}\)
2 Ethyl alcohol
3 Secondary alcohol
4 Tertiary alcohol
Explanation:
Primary alcohol is most reactive for the reaction due to breaking of \(\mathrm{O}-\mathrm{H}\) bond.

Among the following compounds, the strongest acid is
1 \(\mathrm{CH} \equiv \mathrm{CH}\)
2 \(\mathrm{C}_{6} \mathrm{H}_{6}\)
3 \(\mathrm{C}_{2} \mathrm{H}_{6}\)
4 \(\mathrm{CH}_{3} \mathrm{OH}\)
Explanation:
Alcohols are more acidic than hydrocarbons due to more polar nature of \(-\mathrm{OH}\) bond.

The best reagent for the preparation of sodium alkoxide from alcohol is
1 \(\mathrm{NaH}\)
2 \(\mathrm{NaNH}_{2}\)
3 \(\mathrm{Na}\) metal
4 \(\mathrm{Na} / \mathrm{HOH}\)
Explanation:
\(\mathrm{NaH}\) is most basic in character.

Assertion : Alcohols react with acid anhydride and acid chloride to form esters. Reason : Dissociation constants of alcohols are higher than the dissociation constant of water.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Alcohols exhibit lower dissociation constants than water, indicating their weaker acidity compared to water. So the option (3) is correct.
