Ans: Option (ii)
In a molecular structure if a central atom has the same hybridization as the central atom of another molecular species, then the two structures are known as isostructural species.
(i) In NF3 the central nitrogen atom is sp3 hybridized and in BF3 the central boron atom is sp2 . So, these two molecules are not isostructural pairs.
(ii) In BF4 the central boron atom is sp3 hybridized and in NH4 + the central nitrogen atom is also sp3 So, these two molecules are identified as isostructural pairs.
(iii) In BCl3 the central boron atom is sp2 hybridized and in

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.
