Question

Mark the fraction of Coal Tar distillation in which benzene and toluene both are:

• A. Light oil
• B. Middle oil
• C. Heavy oil
• D. Anthracene oil

Answer 1

The correct option is A Light oil

Table:

Name of the fraction Temperature range ( K ) Main Constituents

Light oil (or crude oil) fraction	Upto 443	Benzene, toluene, xylene
Middle oil fraction (Carbolic oil)	443-503	Phenol, naphthalene, pyridine
Heavy oil fraction (Creosote oil)	503-543	Naphthalene, naphthol and cresol
Green oil (Anthracene oil)	543-633	Anthracene, phenanthrene
Pitch (left as residue)	Non-volatile	Carbon

From the table, it is clear that fraction of Coal Tar distillation in which benzene and toluene both are Light Oil.

Hence, option A is Correct.
