the comparison of the properties between covalent compounds and ionic compounds, i.e. m.p., b.p., conductivity.
最佳解答:
For covalent ones: 1-mp/bp: similar 2-conductivity: no 3-solubility:some of them soluble in organic solvent 4-bonding: covalent bond between each atom (some's a giant network structure,like C14) 5-components: non metal elements For ionic ones: 1-mp/bp:similar 2-conductivity : electrical when dissloved in solvent 3-solubility: soluble in water and some,either inorganic solvent 4-bonding: ionic bond between each atom to form giant ionic structure 5-components: non metal elements and metal elements
其他解答:
covalent: (1)simple molecular structure -mp low,bp low -conductivity=0 (2)giant molecular structure -mp/bp high -conductivity=0 ionic mp/bp high conductivity=0 if solid;only conduct electricity in molten/aqueous state
