SOLVED:Consider the halogens chlorine, bromine, and iodine. The melting point and boiling point of chlorine are -101.0^∘ C and -34.6^∘ C while those of iodine are 113.5^∘ C and 184.4^∘ C, respectively. Thus, chlorine is a gas and iodine is a solid under room conditions. Estimate the melting point and boiling point of bromine. Compare your values with those from a handbook of chemistry.
