Is there a specific structure/formula for petroleum ether/ligroin? What is it primarily composed of? My teacher said it is primarily hydrocarbon (hexanes). Is this true?

First, petroleum ether/ligrin is not an ether ( a molecule containing --CH2--O--CH2 ) it is a hydrocarbon distillation fraction mostly C6 hydrocarbons and its isomers, but also some C5 and some C7 hydrocarbons as well.
