Reorder

Reorder the correct step in identifying the molecular geometry.

• Determine the total number of valence electron (VE) in a molecule.

• Draw the skeletal structure of the molecule (assuming all are single bond) and determine the bonded electrons (BE). 1 bond = 2 e-

• Determine the required electrons (RE)

• Calculate the available electrons (AE) for distribution using the formula AE = VET – RE

• Determine the number of bonds or lone pair electrons around the central atom. (LP/BP = $$\frac{𝐵𝐸−𝐴𝐸}{2}$$
