Due to less polarizability of fluorine, it boils at _.
Correct answer: A. -188.1
- A. -188.1
- B. 188.1
- C. -184.4
- D. 184.4
Explanation
Polarizability increases with increase in atomic and molecular size, among halogens fluorine has less polarizability so it boils at -188.1oC.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
