14.2 Hybridization

Question 1

Hybridization

Answer 1

Mixing of atomic orbitals to produce hybrid orbitals used for bonding
1) Hybrid orbitals only form sigma bonds

Question 2

sp3 Hybridization

Answer 2

1) 4 sp3 orbitals =3 p orbitals + 1 s orbital
2) All have the same energy
3) Electron domains= 4
4) Electron domain geometry= Tetrahedral
5) Molecular geometry= Tetrahedral, bent, trigonal pyramidal.
6) Bond angle= less than equal to 109.5

Question 3
