WebDimethylpropane or neopentane has a tetrahedral structure, giving it lower surface area with which to interact with other molecules by london dispersion forces. If you were to compare isopentane with both of them you would find it to be between them, higher than neopentane but lower than n-pentane, for the same reason. More WebNotice that n-pentane is roughly sausage-shaped, whereas neopentane is a spherical ball. Neopentane molecules pack better into a crystalline lattice, so more energy is required to melt the solid; thus its melting point is the highest of the three isomers.
