Aldehydes Ketones Question 25
Question: Which of the following compounds will react with $ NaHCO_3 $ solution to give sodium salt and carbon dioxide-
Options:
A) Acetic acid
B) n-Hexanol
C) Phenol
D) Both [b] and [c]
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Only acetic acid is more acidic than carbonic acid (conjugate acid of $ NaHCO_3 $ ) hence it dissolves in $ NaHCO_3 $
$ \underset{strongeracid}{\mathop{CH_3COOH}}+NaHCO_3\xrightarrow{{}} $
$ CH_3CO{O^{-}}N{a^{+}}+\underset{weakeracid}{\mathop{H_2CO_3}}( H_2O+CO_2 ) $ while phenol and n-hexanol are less acidic than carbonic acid and hence do not dissolve in $ NaHCO_3 $ .
