If ΔEN< 1.5, bond is covalent.D-G Assign needed (N), available (A), shared electrons (S) and bond sites (B) for Lewis dot determinationH Does structure follow octet rule. If yes, then answer J and K as below.I Double or triple bonds in molecule is S/2/B is integer > 1J Resonance if (S/2)/B is not an integerK Create Lewis dot structureL Count regions of electron density to perform VSEPR and VB determinationsM-O Electronic geometry, hybridization bond angle from regions of electron densityP-R Bonding and nonbonding electron pairs around central atom and molecular geometry that results.S Draw VSEPR 3-D structure including all available electrons (column E)T,U Draw VSEPR 3-D structure with dipole moments (ΔEN) from column B. If ΣΔEN=0, then non-polar, ΣΔEN ≠ 0 then polar.Create your own moleculesABCDEFGHIJKLMNOPQRSTUNamemolecularInitial layoutEN valuesIonic orNASBOctet rule?Double or tripleResonance?Lewis dotstructure#e- rich regionsElectronicgeometryHybridizationBond angleBonding pairsUnbonded
