A compound liberates \[C{{O}_{2}}\]with \[NaHC{{O}_{3}}\]and also gives colour with neutral\[FeC{{l}_{3}}\]solution. The compound can be

A)            

B)  

C)             

D)  

Correct Answer: B

Solution :

          The compound liberates \[C{{O}_{2}}\]with \[NaHC{{O}_{3}},\] so it contains \[-\,COOH\]group and it also gives colour with neutral \[FeC{{l}_{3}}\] solution, so it also contains a \[-\,OH\] group directly attached to the benzene ring (i.e., phenol). Hence, the structure of the compound is
