The strongest intermolecular interactions between pentane (C5H12) molecules arise from

A.dipole-dipole forces.

B. London dispersion forces.

C. hydrogen bonding.

D.ion-dipole interactions.

E.carbon-carbon bonds

Ansewr:

option B : London dispersion forces

Step-by-step explanation

Pentane has no dipole or induced dipole. It don't have any hydrogen bonding too, neither it have ion interaction

only interaction between pentane molecules is london dispersion forces.

The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

Also, C-C bond is not an inter-molecular bond.

So, correct choice is

option B : London dispersion forces
