Question

Which of the following statements are true and which are false? A sigma molecular orbital (as compared to a pi molecular orbital)...

1.)may result from overlap of two sp2 orbitals.
2.)may be bonding or anti-bonding.
3.)does not have a single lobe of electron density.
4.)may have delocalized electrons in conjugated compounds.
5.)may result from an atomic p orbital and a sp2 orbital.
6.)may not result from two atomic p-orbitals.

Answer 1

1.)may result from overlap of two sp2 orbitals.

2.)may be bonding or anti-bonding.

6.)may not result from two atomic p-orbitals.

Answer 2

may result from head-on overlaping of atomic orbitals
