arrange the following for Boiling point.
n-pentane , 2 methyl butane , 2,2-dimethyl propane, pentene , pentyne

Solution

The boiling point order is Alkynes > Alkene > Alkane

In alkane, more the surface area more will be the boiling point. So for the given compound, n-pentane, 2-methylbutane, 2,2-dimethylpropane, the surface area are in the order

Pentane > 2-methylbutane > 2,2-dimethylpropane.

So the given compounds exist wilth boiling point order as

Pentyne > Pentene > n-pentane > 2-methyl butane > 2,2 -dimethylpropane
