Answer

Explanation:

Step1: Understand intermolecular forces

Larger non - polar molecules have stronger London dispersion forces.

Step2: Compare molecular sizes

Octane ($C_8H_{18}$) has a larger molecular size than butane ($C_4H_{10}$) as it has more carbon and hydrogen atoms.

Step3: Relate to melting point

Stronger intermolecular forces lead to higher melting points. Since octane has stronger London dispersion forces due to its larger size, its melting point is higher.

Answer:

The melting point is higher for octane.
