1. Section 3: Molecular Geometry

2.  Multiple Bonds – occur in covalent compounds when atoms share more than one pair of electrons  Double Bond – atoms share 2 pairs of electrons  Triple Bond – atoms share 3 pairs of electrons

3.  The more bonds between 2 atoms, the stronger the bond  The more bonds between 2 atoms, the shorter the length of the bonds Bond Strength  Single Bond < Double Bond < Triple Bond Bond Length  Single Bond > Double Bond > Triple Bond

4.  States that repulsion between valence electrons causes electron pairs/bonds to be placed as far apart as possible.  Electrons have the same charge, which causes them to repel each other

5.  Electrons repelling leads to unique angles between atoms in the molecule. ▪ Bond Angle – angle made between two adjacent atoms in a molecule  Bending of molecules leads to specific molecular shapes…
