Rules of VSEPR Theory 1)Draw the best Lewis dot structure of the molecule 2)Assign a steric number(SN)to the structure SN =(of bonded atoms)+(of lone pairs) 3)Place the atoms and lone pairs as far apart as possible (while still keeping them connected to the central atom) 4)Deduce the molecular geometry by ignoring the positions of the lone pairs 5)Remember,lone pairs are FAT VIll-5Rules of VSEPR Theory 1) Draw the best Lewis dot structure of the molecule 2) Assign a steric number (SN) to the structure SN = (# of bonded atoms) + (# of lone pairs) 3) Place the atoms and lone pairs as far apart as possible (while still keeping them connected to the central atom) 4) Deduce the molecular geometry by ignoring the positions of the lone pairs 5) Remember, lone pairs are FAT VIII-5
