Interpretation Introduction

Interpretation:

Whether the given statement is valid or not should be determined.

Concept Introduction:

The ionization of the elements present in a compound depends upon several factors. The ionization is parallel to the polarization thus a more polarize molecule leads to ionic compound i.e. permanent presence of two ions in the compound which is pictorial can be shown as:

Thus more polarisability in the molecule leads to the formation of an ionic compound and vice-versa. The attaining covalent character by ionic compounds as a consequence of polarization may be generalized in terms of Fazan’s rules. According to which an ion will form more easily when-
(i) The electronic structure of the ion is stable.
(ii) The charge on the ion is small.
(iii) A small atom forms the anion and a large atom forms the cation.
Thus the covalent character in a molecule will be favorable when-
(i) The ions have high charge
(ii) The small size of the cation and large size of the anion.
(iii) The cations with 18 electrons structures.
(iv) The compound will be less soluble in a polar solvent like water.
