Question

A compound 'A' gives violet color with $FeCl_3$ solution. Upon nitration with dilute $HNO_3$, it generates two isomers, (X) and (Y), which are separable by steam distillation. Reaction of compound 'A' with bromine water gives a white ppt of compound 'Z'. The combined total number of carbon, oxygen and bromine atoms present in compound 'Z' is __.

Answer 1

10

Answer 2

Compound 'A' is identified as phenol ($C_6H_5OH$) due to its positive $FeCl_3$ test and its nitration products (o- and p-nitrophenol) being separable by steam distillation. Phenol reacts with bromine water to form 2,4,6-tribromophenol ($C_6H_3Br_3O$) as a white precipitate 'Z'. Counting the atoms in $C_6H_3Br_3O$, there are 6 Carbon, 1 Oxygen, and 3 Bromine atoms. The sum is 6 + 1 + 3 = 10.
