Explain the regiochemical outcome for chlorination of bromobenzene. Ortho attack and para attack are preferred because each of these pathways involves a sigma complex withresonance structures. Attack at the meta position involves formation of a sigma complex with only resonance structures. The reaction will proceed more rapidly via the energy sigma complex, so attack takes place at the ortho and para positions in preference to the meta position.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
