Question

Which of these will not react with acetylene?

• A. $NaOH$
• B. Ammoniacal $AgN{O}_3$
• C. $Na$
• D. $HCl$

Answer 1

Answer: (A)

$NaOH$

Acetylene does not react with NaOH because the product will be stronger acid H${}_2$O and the stronger basic salt $(CH\equiv {CNa}^{+})$

Formation of a strong acid is not possible in acid-base neutralisation reaction of a weak acid. Hence, acetylene will not react with NaOH.

Hence, the correct option is $\text{A}$
