Question

Assign a formal charge to each atom of AsCl3

Answer 1

As = 5+; Cl = 1-

As = 5-; Cl = 7+

As = 0; Cl = 0

As = 3+; Cl = 1-

As = 6+; Cl = 2-

Answer 2

You know that chlorine carries a 1\(^-\) charge, but you have 3, so you have 3\(^-\)! Now, to make this neutral, that means that you must have a what charge for As to make the overall charge = 0?

Answer 3

+3
