Question


How many electrons are shared in a double bond?

  1. 1
  2. 2
  3. 4
  4. 6

Hint:

Each bond is formed by sharing 2 electrons.

The correct answer is: 4


    • Covalent bonds are formed by sharing of valence electrons.
    • Each bond is formed by sharing of two electrons.
    • Here it is a double bond. Hence, it is formed by sharing 4 electrons.
