The size of molecular chlorine is about ...

The size of molecular chlorine is about `3.5A^@`. At what maximum intermolecular distance the dispersion forces operate?

Text Solution

Verified by Experts

One-half of the size is taken as .r.
.r. 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 inter-molecular forces operate in chlorine is approximately 300 pm.

What are dispersion forces ?

The intermolecular forces operating between two constituent particles depends on the distance between the centres of the molecules. Dipole-dipole interactions are inversely proportional to 3rd power of the distance where as dipole induced dipole interaction are inversely proportional to the sixth power of intermolecular distances. The forces in dry ice are proportional to (r = intermolecular distance)
