Question 1

How do you determine what orbitals are used to form a bond?

Answer 1

Count the number of groups (atoms and lone pairs)

4 groups - sp3
3 groups - sp2
2 groups - sp
H atom - 1s (no hybridization)

Question 2

If you had a C with 3 groups, singularly bonded to a H atom, what orbital would be used to form this bond?

Answer 2

Csp2 — H1s

Question 3

If you’re determining which orbital is used for a double or triple bond, what components must you include?

Answer 3

The sigma bond and the pi bond

The sigma bond is the normal one, the pi bond is normally something like Cp — Cp

Question 4

What percentage of s-character does each hybridization have?

a) sp3
b) sp2
c) sp

Answer 4

a) 25% s-character
b) 33% s-character
c) 50% s-character
