How many peaks will be present in a mass spectrum for brcl?

Answer:in a mass spectrum of BrCl four (4) peaks will be present

Explanation:

Cl and Br both have two naturally occuring isotopes. Br has 79Br which has abundance50.69% and 81Br which has abundance 49.31%. Similarly two isotopes of Cl are 35Cl having abundance 75.77% and 37Cl having abundance 24.23%. Chlorine and bromine combine and form bromine monochloride. Now they can combine with each other in four possible combinations wich are 1 (81Br37Cl) 2 (81Br35Cl) 3 (79Br37Cl) 4 (79Br35Cl). So these four combined isotopes will show four peaks in mass spectrum.
