Ans: Option (iii) and (iv)
(i) The hybridization of the central carbon atom in CO3 2- is 2 sp as the carbon is bonded with three oxygen atoms. So, the given statement is incorrect.
(ii) The resonance structure of CO32- has one C= O double bonds and two C- O single bonds. So, the statement is incorrect.
(iii) The net charge on three oxygen atoms is -2, hence the average formal charge on each oxygen atom is 0.67 units. So, the given statement is correct.
(iv) As it can be seen from the resonating structures that the structures of the bonds are not fixed. Hence, all the C-

The three fundamental laws of chemistry are - Law of Definite Proportions, Law of Conservation of Mass, and Law of Multiple Proportions.
The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.
