How do I calculate orbital hybridization?

Answer 1

Do you have a problem in mind?

Answer 2

for BF3 and CH4

Answer 3

For CH4 you have hybridized 1s and 3p orbitals; therefore, the hybrid orbitals are 25%s (1/4) character and 75%p (3/4) character.

Answer 4

I don't understand that, can you explain it more fully?

Answer 5

1s + 3p hydbridized to make 4 sp3 orbitals.
s character is 1 out of 4 which is 1/4 and 1/4 is 25%.
3p out of 4 is 3/4 p character which is 75%. Divide it out on your calculator. (3/4)*100 = 75%
(1/4)*100 = 25%.
