Question

Based on the type or types of intermolecular forces, predict the substance in each pair that has the higher boiling point. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before substance Given the molecules propane (CH_3 CH_2 OCH_2 CH_3) and 1-butanol (CH_3 CH_2 CH_2 CH_2 OH). has the higher boiling point mainly due to . Given the molecules propane (C_3H_8) and n-butane (C_4 H_10). has the higher boiling point mainly due to .

Explanation / Answer

We have,

Molar mass of phosgene (Cl2CO) = 98.92 g/mol

Molar mass of formaldehyde (H2CO) = 30.031 g/mol

Molar mass of sulfur dioxide (SO2) = 64.066 g/mol

Molar mass of sulfur trioxide (SO3) = 80.066 g/mol

Therefore, the answer would be,

Given the molecules phosgene (Cl2CO) and formaldehyde (H2CO), phosgene (Cl2CO) has the higher boiling point mainly due to its greater molar mass and stronger dispersion forces.

Given the molecules sulfur dioxide (SO2) and sulfur trioxide (SO3), sulfur trioxide (SO3) has the higher boiling point mainly due to its greater molar mass and stronger dispersion forces.
