2,2–dimethylpropane, C(CH3)4, is an isomer of pentane, CH3(CH2)3CH3. Pentane has a boiling point of 36 °C whilst the boiling point of 2,2–dimethylpropane is 10 °C.

The statement that explains the difference in the boiling points for these two substances is: 

1.  The molecules have different relative molecular masses.
2. Isomers have different chemical properties.
3. Pentane has permanent dipoles.
4. Longer chain, lesser branched molecules have stronger spontaneous/induced dipoles.
