Which of the following statements concerning hybrid orbitals is/are CORRECT?

1. The number of hybrid orbitals equals the number of atomic orbitals that are used to
    create the hybrids.

2. When atomic orbitals are hybridized, the s orbital and at least one p orbital are
    always hybridized.

3. To create tetrahedral structures, the s orbital and all three p orbitals must be
    hybridized..

the only answer I can say for sure is b.  Every example I have gone over requires at least one p orbital.

a. 1 only
b. 2 only
c. 3 only
d. 2 and 3
e. 1, 2, and 3
