A) Acetic acid
B) n-hexanol
C) Phenol
D) Both [b] and [c]
Correct Answer: A
Solution :
[a] Only acetic acid reacts with \[NaHC{{O}_{3}}\] to give sodium salt and \[C{{O}_{2}},\] because \[NaHC{{O}_{3}}\] is a base and it reacts with acid only. |
This is one of the distinguishing test of carboxylic acids. |
\[R-COOH+NaHC{{O}_{3}}\to R-COONa+C{{O}_{2}}\]\[+{{H}_{2}}O\] |
