Question

Taking Mgcl2 as an electrovalent compound,Ccl4 as a covalent compound, give two differences between electrovalent and covalent compounds

Answer 1

Electrovalent  compounds are crystalline solids and conduct electricity in molten state. They dissolve only in water. They have high melting and boiling points

Covalent compounds are mostly fluids(liquids or gases). They dissolve in organic solutions . They have low melting and boiling points.
