Acetic acid

Vedclass · Answer

(C) The reaction with $NaHCO_3$ is a characteristic test for carboxylic acids. Carboxylic acids are stronger acids than carbonic acid $(H_2CO_3)$,which is formed when $NaHCO_3$ reacts with an acid. Acetic acid $(CH_3COOH)$ is a carboxylic acid and reacts with $NaHCO_3$ to evolve $CO_2$ gas: $CH_3COOH + NaHCO_3 \rightarrow CH_3COONa + H_2O + CO_2 \uparrow$. Phenol is a much weaker acid than carbonic acid and does not react with $NaHCO_3$. $n$-hexanol is an alcohol and is even less acidic than phenol,so it also does not react with $NaHCO_3$. Therefore,only acetic acid reacts with $NaHCO_3$ to produce $CO_2$.

Which of the following substances among phenol,acetic acid,and $n$-hexanol will react with $NaHCO_3$ solution to produce a sodium salt and $CO_2$?
