Which substance below has the greatest intermolecular forces? O oxygen with a boiling point of -183°C
O water with a boiling point of 100°C
O gold with a boiling point of 2,970°C
O mercury with a boiling point of 357°C

Oxygen with a boiling point of -183°C.

Explanation:

Higher the intermolecular forces between the liquid particles, more durable it's for it to flee into the vapor part,you would like a lot of energy to convert it from liquid to the vapor part, in different words, higher its boiling point.

Hope it helps!<3

i'm pretty sure its b i might be wrong though!
