Solution
Answer
7σ+3π
Explanation :
This is a molecule of cumulene, C
4

H
4

Single bonds are one σ-bond, while double bonds are oneσ and one π bond
σandπbonds are just ways in which electron orbitals interact to form bonds –
σare stronger bonds, but you can’t have more than one between the same two atoms.
Cumulene has three double bonds and four single bonds, or,
3(σ+π)+4σ=7σ+3π
