Given that both are non-polar and also have actually identical chemical formulas (C5H12), the factor that n-pentane has a greater boiling suggest is that

1. it has actually even more H-bonding than the neopentane.

You are watching: N-pentane polar or nonpolar

2. it has actually more C-H bonds that are slightly polar.

3. its straight-chain framework enables for an extensive long-term dipole.

4. its straight-chain framework enables the molecules to have actually more instantaneous dipoles communicating at close distances.

5. n-pentane has actually even more valence electrons and also therefore deserve to develop even more instantaneous dipoles.
