Question

Two physical problem of covalent compounds

Answer 1

1) covalent compounds are made by sharing of electrons between atoms so they have low melting and boiling point.
2) covalent compounds are nonconductive they don't Conduct electricity or heat.

Answer 2

covalent bonds r formed by the sharing of electrons between atoms .compound that r made of covalent bond have low melting point nd boiling points r non conductive nd non soluble in water.
covalent bonds r weak than ionic bond that's reason behind low mp nd bp. during covalent bond no ions r formed.
