Two atoms share two pairs of electrons between them. What is that bond called?
AA single bond
BA double bond
CA triple bond
DAn ionic bond
Answer & Solution
Correct answer: B. A double bond
1. One shared pair between two atoms makes a single bond.
2. Two shared pairs between the same two atoms make a double bond.
3. Three shared pairs would make a triple bond instead.
4. The carbon to oxygen link in formaldehyde is a familiar example of a double bond.
