Are the following statements true or false? A pi bond consists of two pairs of electrons. A triple bond consists of one pi bond and two sigma bonds. End-to-end overlap results in a bond with electron density above and below the bond axis. Two pi bonds comprise a double bond. A sigma bond allows rotation about its bond axis. Bonds formed from atomic p orbitals are always sigma bonds.
