A petroleum fraction having boiling range 70 − 200 o   C and containing 6 − 10 carbon atoms per molecule is called

Step-by-step solution

The bulk of a typical gasoline consists of hydrocarbons with between 4 and 12 carbon atoms per molecule (commonly referred to as C4 − C12 ). It is a mixture of paraffins (alkanes), cycloalkanes (naphthenes), and olefins (alkenes), where the usage of the terms paraffin and olefin is particular to the oil industry. The actual ratio depends on: The oil refinery that makes the gasoline, as not all refineries have the same set of processing units; The crude oil feed used by the refinery; The grade of gasoline, in
