WebThe boiling points for the "straight chain" isomers and isoalkanes isomers are shown to demonstrate that branching decreases the surfaces area, weakens the IMFs, and lowers the boiling point. This next diagrams summarizes the physical states of the first six alkanes. WebThe position of the branching also has an effect on steric hindrance.The closer the methyl group is to the carboxyl, the more steric hindrance should be.This should be reflected in a lower boiling point. (For comparison, ketones will be used.Boiling points of branched C7H14O aldehydes were difficult to locate.
