A bond formed when two pairs of electrons are shared between two atoms is called a

• A. Single Bond
• B. Double Bond
• C. Triple Bond
• D. Coordinate Bond

Answer: (B)

When two atoms share electrons to fill their outer shells, the number of electron pairs shared between them determines the bond type. Sharing two pairs of electrons between the same two atoms forms a double bond. This is seen in molecules like ethene, where the carbon–carbon connection is represented by two lines and consists of one sigma bond and one pi bond. A single bond uses one pair, a triple bond uses three pairs. A coordinate bond is a covalent bond where both electrons come from the same atom, which is a special case and not defined by having two shared pairs. So the two-pair sharing situation is what defines a double bond.
