Which of the following is not true?

Question

a) The sp3 hybrid orbitals are degenerate.

b) An sp3 hybrid orbital may hold a lone pair of electrons.

c) An sp3 hybrid orbital may form a sigma bond by overlap with an orbital on another atom.

d) An sp3 hybrid orbital may form a pi bond by overlap with an orbital on another atom.

Answer 1

a is not true. Hybrid orbitals are not degenerate whereas atomic orbitals are degenerate. For example, the 3 2p orbitals or the 5 3d orbitals are degenerate. Check out the other three answers. You could Google the questions.

Answer 2

I did google the question, I only ask the question on here to double check.

I get a lot of conflictory answers on Google.
