(a,b)
a. Phenol is also called carbolic acid
Benzoic acid is more acidic than phenol. So the acid reacts with to give
(g), while phenol does not react
b. Acids give buff-coloured precipitate with neutral , while phenol gives violet colouration with neutral
solution, e.g.,
(Ferric benzoate)
(Buff coloured ppt.)
(Ferric Phenoxide)
(Violet colouration)
c. Both acid and phenol react with aqueous to give their corresponding salts
d. Both acid and phenol react with
(Benzamide)
+
(Aniline)
So the answers are (a) and (b)
