Answer 1

(i) The Electrovalent compounds are generally crystalline in the nature. The constituent ions are arranged in a regular way in their lattice.

(ii) The Electrovalent compounds have high melting and boiling points. Order of melting and boiling points in halides of sodium and oxides of IInd group elements.

(iii) The Electrovalent compounds are hard and brittle in nature.

(iv) The Electrovalent solids do not conduct electricity. While the electrovalent compounds in the molten state or in solution conduct electricity.

(v) The Electrovalent compounds are fairly soluble in the polar solvents and insoluble in non-polar solvents.
