Question 1 Give few properties of covalent compounds? Properties of covalent compounds 1)Covalent compounds exist as single molecules which are mostly in gaseous state(hydrogen,oxygen, ammonia).Some of them may be liquid(bromine) and few as solids(iodine, phosphorus) 2)Covalent compounds have usually low melting and boiling point.Since no ions are present in the … [Read more...] about Properties of covalent compounds
