Q.
Two aromatic compounds having foemula $C_{7}H_{8}O\$which are easily identifiable by $FeCI_{3}$ solution test (violet colouration) are
A) o-cresol and benzyl alcohol
B) m-cresol and p-cresol
C) o-cresol and p-cresol
D) Methyl phenyl ether and benzyl alcohol
Explanation
(a)
o-cresol contains phenolic group, thus it gives violet colouration with $FeCl_{3}$ where as benzyl alcohol donot contains phenolic group, hence no colouration with $FeCl_{3}$. Hence, identifiable.
