7. π electron is an electron which resides in the pi bond(s) of a double bond or a triple bond, or in a conjugated p orbital. The 1,3,5-hexatriene molecule is a conjugated molecule with 6 t electrons. Consider the Tt electrons free to move back and forth along the molecule through the delocalized pi system. Using the particle in a box approximation, treat the carbon chain as a linear one-dimensional "box". Allow each energy level in the box to hold...

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.
