In which type of bond are two pairs of electrons shared between two atoms?

• A. Single bond
• B. Triple bond
• C. Double bond
• D. Covalent bond

Answer: (C)

A double bond is formed when two pairs of electrons are shared between two atoms. This type of bond involves four electrons total, where each atom contributes two electrons to the bond, resulting in a stronger connection than a single bond, which only involves one pair of electrons. Double bonds typically occur in molecules like oxygen (O2) and ethylene (C2H4), allowing for greater stability and certain geometric configurations in the resulting structures. While all covalent bonds involve the sharing of electrons, the term 'covalent bond' is a broader category that encompasses single, double, and triple bonds. A single bond entails the sharing of only one pair of electrons, and a triple bond involves the sharing of three pairs of electrons. Therefore, in the context of the question, referring specifically to two pairs of shared electrons directly points to a double bond.
