What are the intermolecular forces that operate in isomeric C4H9Cl?

This is an experimental proposition for which we need data, which we ain't got.

Explanation:

We would ASSUME here that the longest chain isomer has the LOWEST volatility and the greatest normal boiling point.....

H3C−CH2CH2CH2Cl; boiling point=78 ∘C

H3C−CHClCH2CH3; boiling point=70 ∘C

H3C−CH(CH3)CH2Cl; boiling point=69 ∘C

(H3C)3C−Cl; boiling point=51 ∘C.

Are there are only 4 isomers of butyl chloride? Are my boiling points right? Do not assume that I have got it right.

SO why the difference in volatility? Tert butyl chloride has the least longest carbon chain of the given isomers, and therefore the least potential for van der Waal's interactions.
