Question

How many bonds are formed between two carbon atoms with 4 shared electrons?

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

Answer 1

The correct option is B 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.
