which statement best compares the melting point of butane (c₄h₁₀) with that of octane (c₈h₁₈)? the melting points of both substances are identical. the melting point is higher for butane. the melting point is higher for octane. the comparison of melting points cannot be made.

which statement best compares the melting point of butane (c₄h₁₀) with that of octane (c₈h₁₈)? the melting points of both substances are identical. the melting point is higher for butane. the melting point is higher for octane. the comparison of melting points cannot be made.

Answer

Brief Explanations:

Melting point of hydrocarbons increases with increasing molecular weight. Octane ($C_8H_{18}$) has a higher molecular weight than butane ($C_4H_{10}$) due to more carbon - hydrogen atoms. Stronger London - dispersion forces in octane result in a higher melting point.

Answer:

The melting point is higher for octane.
