Can someone provide me with a step by step solution as to how I can solve any of these problems from start to finish so that I have a good methodology? We see that H 2 O, HF, and NH 3 each have higher boiling points than the same compound formed between hydrogen and the next element moving down its respective group, indicating that the former have greater . Direct link to Yuya Fujikawa's post I think that's a good poi, Posted 7 years ago. Compounds II and III only exhibit intermolecular London dispersion forces, so they would be the two lowest boiling compounds (weakest intermolecular forces). this causes intermolecular forces of attraction to go up.

CH3CH2CH2CH2CH3 This can account for the relatively low ability of Cl to form hydrogen bonds. If you are comparing molecules to determine which has the higher boiling point, consider the forces that are at work within the molecule. pressure. E) strong enough to hold molecules relatively close together, Which molecule has hydrogen bonding as the predominant intermolecular force? statement were true, would it lead to the boiling The trend of lower atomic (molar) mass having a lower boiling point can be applied only to Q4 because all answers are homo diatomic molecules. The boiling point of a compound is influenced by several factors. A. II > IV > I > III When something boils, you're not actually breaking any of the covalent bonds, so that doesn't explain anything I know that the highest boiling point has to do with which has the strongest intermolecular force.
