- Q2At 298 K and 1 atm, Br2 is a liquid and Cl2 is a gas. Those observations provide evidence that under the given conditions, theforces among Br2 molecules are stronger than those among Cl2 moleculesforces among Cl2 molecules are stronger than the Cl−Cl bondCl−Cl bond is stronger than the Br−Br bondBr−Br bond is stronger than the Cl−Cl bond60s
