2 pi bonds

The bonding scheme varies depending on the molecule
|
Detailed explanation-1: -Double bonds are comprised of one sigma and one pi bond. Triple bonds are comprised of one sigma bond and two pi bonds.
Detailed explanation-2: -In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes.
Detailed explanation-3: -Answer and Explanation: When two electrons pairs are shared by two atoms, then they will form a double bond. For example, the ethene molecule contains a double bond. This double bond will have one sigma bond and one pi-bond.
Detailed explanation-4: -The sp2 hybridization facilitates a double bond between the carbons because it allows an sp2 orbital to overlap through a sigma bond and the unhybridized py orbitals for each carbon to also overlap. This p orbital overlap is a pi bond.
