Question

What is the polarity of `Cl_2O`?

Answer 1

There is a permanent dipole moment in the `Cl_2O` molecule, analogous (but much less in magnitude) to that of the water molecule.

Explanation:

And thus we draw `stackrel(delta+)Cl-stackrel(delta-)O-stackrel(delta+)Cl` in that oxygen is SLIGHTLY more electronegative than chlorine.

`/_Cl-O-Cl=110.9^@`, and `Cl-O=1.70xx10^-10*m`.
