1.	Why can sugar (sucrose) melts on heating but common salt (sodium chloride) doesnot melt so easily ?
Answer» Solution :Common salt (NaCl) is an ionic compound in which `Na^(+)` ions and `Cl^(-)` ions are held together by strong electrostatic forces of attraction. Hence, its MELTING point is very high. SUCROSE is a covalent compound and no ions are present. Molecules are held together by WEAK van der Waal forces and hydrogen bonds. Hence, it has LOW melting point.
