Final answer:
The literature melting point of naphthalene is 80.2°C, and its molecular formula is C10H8, which contributes to its relatively high melting point.
Step-by-step explanation:
The literature melting point of naphthalene is 80.2°C. This compound, which is known for being the active ingredient in traditional mothballs, has the molecular formula of C10H8. Naphthalene's molecules exhibit strong London dispersion forces due to their flat, aromatic structure, which contributes to their relatively high melting point compared to nonaromatic hydrocarbons with similar molar masses.
