Question

For each of the following cations,  draw the Lewis structure,  predict the molecular geometry and the bond angles by using the VSEPR model, and  determine whether or not the molecule is polar. (If the molecule IS polar, indicate the direction of the net molecular dipole.)

BrF4+ (Br is the central atom)

b) PCl4+ (P is the central atom)
