Question

1. which factor contributes to the higher boiling point of ethanol (c₂h₅oh) compared to ethane (c₂h₆)? a. metallic bonding in ethanol b. dipole - dipole interactions in ethane c. hydrogen bonding in ethanol d. london dispersion forces in ethanol

Explanation:

Ethanol ($C_2H_5OH$) has a hydroxyl (-OH) group. The hydrogen atom in the -OH group can form hydrogen bonds with the oxygen atom of another ethanol molecule. Hydrogen bonding is a stronger intermolecular force compared to dipole - dipole interactions and London dispersion forces present in ethane ($C_2H_6$). Metallic bonding is not present in ethanol as it is a covalent compound. Ethane is non - polar and has only London dispersion forces. The stronger hydrogen bonding in ethanol requires more energy to break, resulting in a higher boiling point.

Answer:

C. Hydrogen bonding in ethanol
