Why can sugar (sucrose) melts on heating but common salt (sodium chloride) does not melt so easily ?

Text Solution

Verified by Experts

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.

    While showing some common conpounds used in our daily life in the laboratory, the teacher showed sodium chloride compound and told that it is also called common salt. Next day, one of the students brought common salt from home to the laboratory and requested the teacher to show sodium chloride as well. He kept both common salt and sodium chloride in two different watch glasses and left. Next day, during lunch break the studend went to the laboratory and saw that the common salt brought from home became sticky whereas the compound sodium chloride remained as it is. What would be the justification given by the teacher for the above observation?
