Bond Angles of Covalent Molecules
• Shape and bond angles of molecules depend on:
The number of pairs of electrons around central atom and Whether these pairs are lone pairs or bonded pairs
• Valence shell electrons are arranged in pairs to minimize repulsion between themselves
Order of repulsion strength (VSEPR Theory):
Lone -Lone Lone - Bonded Bonded - Bonded
Type Shape Angle Example:
2 Pairs of electrons
2 bond pairs
Linear 180 degree angle
e.g CO2
3 Pairs of electrons
3 bond pairs
Trigonal Planar 120 degree angle
e.g BF3
4 Pairs of electrons
4 bond pairs
Tetrahedral 109.5 degree angle
e.g CH4
3 bond pairs and 1 lone pair
Pyramidal 107 degree angle
e.g NH3
2 bond pairs and 2 lone pairs
Angular 104.5 degree angle
e.g H2O
5 Pairs of electrons
5 bond pairs
Trigonal Bipyramid 90 degree angle
e.g PF5
6 Pair of electrons
6 bond pairs
Octahedral 90 degree angle
e.g SF6
