Butane, C₄H₁₀ will undergo only London dispersion forces when interacting with other molecules of the same kind.
London dispersion force:
The weakest intermolecular force is called the London dispersion force.
When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the resulting transient attractive attraction is known as the London dispersion force.
There are instances when this force is referred to as an induced dipole-induced dipole attraction.
Butane molecules only exhibit London dispersion forces because they are non-polar and have a symmetrical distribution of electron density.
<u><em>Butane:</em></u>
It is a covalent non-polar molecule. Every C-C and C-H bond is non-polar. This is because there is little or no electronegativity difference between C and C in C-C bonds and none between C and H in C-H bonds.

To me we wouldn't know as much as we do. There is so much they don't want us to know about space. Just watch the moon at night and you can get a better answer.
