Chemistry Unit 3 - Single, Multiple, Sigma, and Pi Bonds

Single bonds have

an electrong density mostly symmetrically around a “line” between bonded nuclei

Where is the internuclear axis located?

Through the middle of the overlap region of the orbitals between two atoms.

Multiple bonds have

more single bonds on same axis

Multiple bonds also have an overlap of

2 orbitals side by side on internuclear axis

What is the probability of finding electrons on an internuclear axis for sigma bonds?

High

What is the probability of finding electrons on an internuclear axis for pi bonds?

None

Which has more overlap between orbitals, sigma or pi?

Sigma bonds

Which is stronger, sigma or pi bonds?

Sigma bonds

pi bonds are typically found with what elements?

C, N, and O

pi bonds are not usually found in which elements?

S, P, and Si
