Question

State 4 points of difference between electrovalent and covalent compound

Answer 1

-Electrovalent compounds are made up of ions.

-Electrovalent compounds are heard, crystalline solids e.g. Na CI, Mg CL2

-Electrovalent compounds are usually soluble in water but insoluble in non-polar solvents like CI4

-Electrovalent compounds generally have high melting and boiling points.

-Covalent compounds are formed by mutual sharing of electrons as in NH3

-Covalent compounds are made up of molecules.

-Covalent compounds are usually liquids or gases. E.g. CH4, C2 H6, NH3

-Covalent compounds are soluble in non-polar solvents like benzene or carbon
