Well, their connectivity.........

Explanation:

We have C5H12, and form this formula we get structural isomers of n-pentane, H3CCH2CH2CHCH3, isopentane, H3C(H3C)CHCH2CH3, and neopentane, (H3C)4C.

In each isomer, the connectivity of the carbon-carbon chain is different. The isomers would have slightly different metling and boiling points, with n-pentane as the LEAST volatile. Why so?
