Question: 1 / 400

What is another name for a double bond?

Single bond

Covalent bond

Pi bond

A double bond is characterized by the sharing of two pairs of electrons between two atoms. This type of bond consists of one sigma bond and one pi bond. The sigma bond is formed by the head-on overlap of orbitals, while the pi bond is formed by the side-to-side overlap of p orbitals. Because a double bond includes both types of bonds, it is accurate to refer to the additional bond formed in a double bond as a pi bond. This distinguishes it from other types of bonds, which do not involve this specific type of electron sharing structure.

Thus, identifying a double bond with the term "pi bond" reflects the role that this type of bond plays within the overall bonding structure of the compound.
