Question

what is straight chain hydrocarbons

Answer 1

 For a given number of carbon atoms, an unbranched alkane has a higher boiling point than any of its branched-chain isomers. This effect is evident upon comparing the boiling points (bp) of selected C 8H 18 isomers.

Answer 2

Substances consisting entirely of single-bonded carbon and hydrogen atoms and lacking functional groups are called alkanes. There are three basic types of structures that classify the alkanes:

1. linear straight-chain alkanes
2.branched alkanes
3.cycloalkanes
