Question

The reason why CO2 is highly stable because it’s ____: 

Options
  • A

    Highly stable

  • B

    Covalent Molecule 

  • C

    Highly reactive 

  • D

    Carbon molecule 

Explanation

In CO2, carbon, and oxygen first form a double covalent bond. At first, oxygen and carbon share their two valence electrons. This makes a double bond. By doing so oxygen becomes stable.
