Dipole-dipole

This is the end of the review for the test on Tuesday 12/13/16.

List the following bonds in order from weakest to strongest: I. permanent dipole-dipole bonds between SO2 molecules II. covalent bonds between carbon and hydrogen in CH4 III. London dispersion forces between atoms of helium IV. Permanent hydrogen bonds between HF molecules V. Covalent bonds between nitrogen atoms in N2 molecules VI. London dispersion forces between molecules of carbon dioxide

III, VI, I, IV, II, V

Identify which molecule in the pair has the higher boiling point and explain: HF and HBr

HF – has hydrogen bonding

Identify which molecule in the pair has the higher boiling point and explain: NH3 and AsH3

NH3 because of hydrogen bonding

Identify which molecule in the pair has the higher boiling point and explain: CH4 and CH3Cl

CH3Cl because of dipole-dipole instead of only London dispersion forces
