Distorting effect of lone pairs Distorting effect of lone pairs W Lone pairs are more negative than bonding pairs and so repel other electrons more Lone pair-lone pair>lone pair-bonding pair>bonding pair-bonding pair W The repulsion “pushes” other electrons out of the way W Example H 2 O AX 2 E 2 – tetrahedral (109.5), but lone pair repulsion makes the bond angle 104°

Multiple bonds Multiple bonds W The order of the bonds doesn’t change the count W Double bonds do have more electron density than single bonds W They repel other electrons more

Multiple central atoms Multiple central atoms W Groups of central atoms may be linked together W Consider one at a time W Example CH 3 CH 3 -ethane each carbon is a central atom H each carbon is a central atom H 3 C -C is tetrahedral C is tetrahedral C-C H 3 is tetrahedral is tetrahedral CH 3 C CH, H 3 C -C, tetrahedral, C C, tetrahedral, C -C C is linear, C is linear, -C C H is linear H is linear
