# Problem: Part A. How many σ and π bonds are present in a molecule of cumulene? Enter the number of σ bonds followed by the number of π bonds separated by a comma.When two atoms form a single covalent bond, two orbitals (one from each atom) overlap such that the electron pair can be in both orbitals simultaneously. Double and triple bonds involve the sharing of multiple electron pairs. Each additional electron pair requires the overlap of another set of orbitals. A set of overlapping orbitals is called a σ bond (sigma bond) if the overlap is head- on and a π bond (pi bond) if the overlap is sideways.

###### Problem Details

Part A. How many σ and π bonds are present in a molecule of cumulene?

Enter the number of σ bonds followed by the number of π bonds separated by a comma.

When two atoms form a single covalent bond, two orbitals (one from each atom) overlap such that the electron pair can be in both orbitals simultaneously. Double and triple bonds involve the sharing of multiple electron pairs. Each additional electron pair requires the overlap of another set of orbitals. A set of overlapping orbitals is called a σ bond (sigma bond) if the overlap is head- on and a π bond (pi bond) if the overlap is sideways.
