Question

1. Predict the types of

intermolecular forces that may act between
the molecules in these substances.
a. CO₂
b. NH,
c. HCI
d. C,H,

Answer 1

a. Due to the non-polar nature of CO2 molecules, London dispersion forces are the only intermolecular forces that may interact with them.

b. Due to the presence of a nitrogen atom with a single pair of electrons, NH3 molecules are polar and are capable of both hydrogen bonding and dipole-dipole interactions.

c. Due to their polar nature, HCl molecules are capable of both hydrogen bonding and dipole-dipole interactions.

d. Since C6H6 (benzene) molecules are non-polar, London dispersion forces are the only intermolecular forces that can act between them.
