The meiting points and boiling points of two isomeric alkanes are as follows: CH3(CH2);CH3, mp = -57 °C and bp = 126 °C; (CHalsCC(CH3)3, mp = 102 °C and bp = 106 °C. (a) Explain why one isomer has a lower melting point but higher boiling point. (b) Explain why there is a small difference in the boiling points of the two compounds, but a huge difference in their melting points.
