Bond Angle

[Verity Lai 2K]

Could someone remind me what the bond angles are for each VSEPR shape?? Thanks!

180 degrees for linear,
120 degrees for trigonal planar, 109.5 degrees for tetrahedral, 120 degrees for the trigonal bond angles and 90 and 180 degrees for the axial bond angles in a trigonal bipyramidal, 90 and 180 degrees for octahedral

Linear: 180
Trigonal planar: 120
Tetrahedral: 109.5
Trigonal bipyramidal: trigonal bond angle: 120, axial bond angle: 90 and 180
Octahedral: 90 and 180

This is a very broad question since there are many, many VSEPR shapes depending on different combinations of numbers of bonding pairs and lone pairs on the central atom. However, for the basic structures with no lone pairs, they are as follows:
2 atoms attached to central atom = linear = 180 degrees between the two attached atoms
3 atoms attached to central atom = trigonal planar = 120 degrees each between the 3 atoms
4 atoms attached to central atom = tetrahedral = 109.5 degrees each between the 4 atoms
5 atoms attached to central atom = trigonal bipyramidal = 90 degrees between those on vertical versus horizontal plane, 180 degrees between the two on the vertical plane, and 120 degrees between the 3 on the horizontal plane. (Imagine a trigonal planar with a linear vertically through the middle)
6 atoms attached to central atom = octahedral = 90 degrees between those on vertical plane versus horizontal plane, 90 degrees between the 4 atoms on the horizontal plane, and 180 degrees between the two on the vertical plane. (imagine a square planar with a linear vertically through the middle)
Keep in mind that these bond angles are only for when the atoms around the central atom are of the same element. They will be slightly different if the elements of the atoms are different due to different repulsions.
Hope this helps!
