Expert Answer

Step 1

1.Given, Pentane has higher molar mass than hexane.

Pentane consists of five carbon atoms whereas hexane consists of six carbon atoms.

The molar mass of pentane is 72.15g/mol and hexane is 86.18g/mol.

Hence, the given statement is FALSE.

Step 2

2.Given, the longer the linear alkyl chain for straight chain hydrocarbons, the higher the boiling point.

Linear alkyl chain increase ...
