Compare carbon tertrachloride and sodium chloride with regards to solubility in water and electrical conductivity.
Carbon teterachloride is covalent compound while sodium chloride is an ionic compound. features of covalent compounds are:
(i) These exist as gases or liquids under the normal conditions of temperature and pressure. Some covalent compounds exist as soft solids.
(ii) In general covalent substances are bad conductor of electricity. Polar covalent compounds like HCl in solution conduct electricity.
(iii) These compounds are generally insoluble in polar solvent like water but soluble in non-polar solvents like benzene etc. some covalent compounds like alcohol, dissolve in water due to hydrogen bonding.
Features of ionic compounds-
(i) Electrovalent compounds are generally crystalline is nature. The constituent ions are arranged in a regular way in their lattice.
(ii) Electrovalent compounds possess high melting and boiling points.
(iii) Electrovalent compounds are hard and brittle in nature.
(iv) Electrovalent solids do not conduct electricity. While electrovalent compounds in the molten state or in solution conduct electricity.
(v) Electrovalent compounds are fairly soluble in polar solvents and insoluble in non-polar solvents.
