A metal and a non-metal form ionic bonds, while two non-metals form covalent bonds.
In 1, Fe is a metal while Cl is a non-metal. Thus, ionic bonds are formed.
In 2, Both C and O are non-metals. Thus, covalent bonds are formed.
In 3, Ca is a metal while Cl is a non-metal. Thus, ionic bonds are formed.
...... The answer is : 2. CO
