Question

A CO₂ molecule contains:

• A. Four pi bonds
• B. Three sigma and one pi bond
• C. Four sigma bonds
• D. Two sigma and two pi bonds

Answer 1

Answer: (D)

The explanation for the correct option:

Option(B) Two sigma and two pi bonds

• The carbon dioxide molecule has two double bonds between the carbon and oxygen atoms.
• Each double bond is made up of one sigma and one pi bond so a carbon dioxide molecule contains two sigma and two pi bonds.
• The structure of carbon dioxide is linear $O=C=O$

Hence, Option(B) Two sigma and two pi bonds, is the correct option, so A $C{O}_2$ molecule contains Two sigma and two pi bonds
