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

Explanation:

We have C_5H_12, and form this formula we get structural isomers of "n-pentane", H_3C-CH_2CH_2CH_"CH_3, "isopentane", H_3C-(H_3C)CHCH_2CH_3, and "neopentane", (H_3C)_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?
