Which of the following can be used to test the acidic nature of ethanol?
1 Blue litmus solution
2 \(\mathrm{Na}_{2} \mathrm{CO}_{3}\)
3 \(\mathrm{NaHCO}_{3}\)
4 \(\mathrm{Na}\) metal
Explanation:
Acidic nature of ethanol can be tested by using active metal such as \(\mathrm{Na}\).On reaction with \(\mathrm{Na}\), evolution of hydrogen gas takes place. \(2 \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}+2 \mathrm{Na} \rightarrow 2 \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{O}^{-} \mathrm{Na}^{+}+\mathrm{H}_{2} \uparrow\)

Assertion : \(\mathrm{CH}_{3} \mathrm{OH}\) is a nucleophile. Reason : \(\mathrm{CH}_{3} \mathrm{OH}\) forms sodium methoxide on reaction with \(\mathrm{NaOH}\).
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:
\(\mathrm{CH}_{3} \mathrm{OH}+\mathrm{NaOH} \rightarrow \mathrm{H}_{3} \mathrm{CO}^{-} \mathrm{Na}^{+}+\mathrm{H}_{2} \mathrm{O}\) Methanol is acidic, The presence of the hydroxy group \((-\mathrm{OH})\) in this molecule means that it can donate a pair of electrons from the oxygen atom. This makes it a potential site for chemical reactions where it can form new bonds by sharing its electron pair with other atoms or molecules, thus functioning as a nucleophile. So the option (2) is correct
