1.	The size of molecular chlorine is about 3.5A^@. At what maximum intermolecular distance the dispersion forces operate?
Answer» Solution :One-half of the size is taken as .r. T. of chlorine is 1.75`A^@` The interaction energy is PROPORTIONAL to `r^(-6)` `r^6` for molecular chlorine `= 2.9A^@` The maximum DISTANCE at which the intermolecular forces operate in chlorine is APPROXIMATELY 300pm.
