Which of the following statements correctly describes the reason why bromine is a liquid at STP, while chlorine is a gas at STP?
- Chlorine gas consists of weak London Dispersion forces, while bromine gas consists of dipole-dipole forces
- Bromine gas has stronger London Dispersion forces, leading to a lower boiling point
- Bromine gas has stronger London Dispersion forces, leading to a higher boiling point
- Chlorine gas is more polarizable than bromine gas is
