E. FALSE

F. FALSE

Explanation:

Are the following statements true or false?

A. Two pi bonds comprise a double bond. FALSE. A double bond is formed by 1 sigma bond and 1 pi bond.

B. Bonds formed from atomic p orbitals are always sigma bonds. FALSE. p orbitals form pi bonds.

C. Side-to-side overlap results in a bond with electron density above and below the bond axis. TRUE. These are pi bonds.

D. A sigma bond allows rotation about its bond axis. TRUE. If the bond is single (sigma bond), the rotation about its bond axis is allowed.

E. A double bond consists of two electrons. FALSE. A double bond consists of 2 pairs of electrons.

F. A triple bond consists of three pi bonds. FALSE. A triple bond consists of 1 sigma bond and 2 pi bonds.
