Question

FILL IN THE BLANK At 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among Br2 molecules are _______ than those among Cl2 molecules

Answer 1

Answer: stronger

Explanation: At higher temperatures, Br2 takes more energy to break apart the molecules. Therefore, the intermolecular forces, most likely london dispersion, will need more energy. Cl2 has weaker forces and takes less to break it apart.
