Question

Check the given reactant conditions and confirm which of the following acid base reaction is not feasible?

• A. $CH\equiv CH+NaOH \rightarrow $
• B. $Ph-OH+NaOH \rightarrow $
• C. $C_{2}H_{5}OH+NaNH_{2} \rightarrow $
• D. $CH_{3}COOH+C_{2}H_{5}ONa \rightarrow $

Answer 1

Answer: (A)

Acetylene is not a regular acid. It has very less tendency to give away its proton.Acetylene is less acidic than water, hence, it cannot react with sodium hydroxide.
$CH\equiv CH+NaOH \rightarrow$ noproducts
It is clear that a sufficiently stronger acid can furnish protons and can displace a weaker acid from the salt. Phenol, ethanol are sufficiently acidic. Lastly, acetic acid is stronger than ethanol.
