• A. Three single bonds
• B. A double bond and a single bond
• C. A triple bond
• D. A double bond

Answer 1

The correct option is D A double bond

A formation of a single bond by sharing of electrons needs the involvement of two electrons. So,

• 2 shared electrons will form a single bond.
• 4 shared electrons will form a double bond.
• 6 shared electrons will form a triple bond.
