Question

Is CO₂ a Covalent Bond?

Answer 1

Chemical bond: The force of attraction that holds different components like atoms, ions, etc. together in different chemical compounds is called chemical bond.

Covalent bond: A chemical bond in which two atoms share an electron pair is called a covalent bond.

• Each combining atom contributes at least one electron to the shared pair.
• A coordination bond is an alternative covalent connection formed when an electron pair is shared from a single atom.
• In this bond the same atom provides both shared electrons. It is also called a dipole bond or a basic bond.

Carbon dioxide(CO₂): Carbon dioxide is a chemical element that can be found in the atmosphere.

• It is found in the gaseous state at room temperature.
• It contains one atom of carbon and two atoms of oxygen.
• 
• The bond between the atoms in a carbon dioxide molecule is a polar covalent bond.
• In a carbon dioxide molecule, one carbon atom is joined by four covalent bonds to two oxygen atoms, each with two covalent bonds.
• The carbon dioxide molecule is held together by the strong C=O.
• Carbon forms double covalent bonds by sharing oxygen electrons.
• There are two bonds each between carbon and oxygen atoms.
• This is called a double bond.
• In carbon dioxide gas because electrons are shared, are not transferred from one atom to another.
• Hence, CO₂ has Polar Covalent Bond.
