are the following statements true or false?
One sigma bond and one pi bond comprise a double bond.
A triple bond consists of one sigma bond and two pi bonds.
End-to-end overlap results in a sigma bond.
A double bond consists of two pairs of electrons.
Bonds formed from atomic p orbitals are always sigma bonds.
A pi bond restricts rotation about the sigma bond axis.

Homework Answers

Answer #1

1) One sigma bond and one pi bond comprise a double bond.= True

2) A triple bond consists of one sigma bond and two pi bonds.= True

3) End-to-end overlap results in a sigma bond. = True.

4) A double bond consists of two pairs of electrons. = True. ( 4 electrons = 2 pairs)

5) Bonds formed from atomic p orbitals are always sigma bonds. = False  because depending on orientation a p- orbital can form either sigma or pi bond.

6)  A pi bond restricts rotation about the sigma bond axis.= True.
