Question

An electrovalent compound does not exhibit space isomerism because of ___________ of the electrovalent bond.
(A) Directional character
(B) Polarity
(C) Non- directional character
(D) Attraction

Answer 1

To answer this question, you must recall the properties of an electrovalent bond. Electrovalent bond is commonly known as ionic bond and is formed by electrostatic attractions between a cation and an anion.

Complete step by step solution
Space isomerism or stereoisomerism is defined as the type of isomerism in which the compounds possessing the same molecular formula as well as the same structural formula, differ in their properties due to the difference in the arrangement of their atoms in space. They usually differ in only their physical properties but not much in the chemical properties. Therefore, we can conclude that the bonds formed must be directional and any change in the arrangement will cause a change in the stereochemistry of the molecule.
Ionic bonds or electrovalent bonds have a non- directional character. This means that the electrostatic field of the ion is spread uniformly in all directions. Thus, the electrostatic attraction acts in all the directions due to which they do not show space isomerism.
Thus, the correct answer is C.

Note
An electrovalent bond is formed by the complete transfer of electrons between two atoms in which an atom donates its electron forming positively charged cation and the other atom accepts the electrons forming a negatively charged anion. Both the charged particles are attracted towards each other and are held together by electrostatic forces.
Generally, an ionic bond is formed between a metal and a non- metal. The metal loses electrons easily and the non- metal accepts electrons easily forming a cation and anion respectively.
