Hybridisation

Question 1

What does sp3 hybridisation involve, its geometry and the number of bonds on the C atom?

Answer 1

One s orbital and three p orbitals combine to give four equivalent sp3 hybrid orbitals. This gives a tetrahedral geometry with bond angles 109.5 degrees and four bonds on each carbon atom

Question 2

What does sp2 hybridisation involve, its geometry and bond angles, and the number of bonds on the carbon atoms?

Answer 2

Two p orbitals and one s orbital to give three sp2 orbitals, giving a trigonal planar geometry with bond angles of 120 degrees, and three bonds on each carbon atom

Question 3

What does sp hybridisation involve, what is its geometry and bond angle, and how many bonds does the carbon atom have?

Answer 3

Involves on s orbital and one p orbital combining to give two sp orbitals. The geometry is linear with a bond angle of 180 degrees. Each carbon atom has two bonds
