Can lone pair electron of simple covalent molecule be mobile?
« on: March 11, 2012, 10:32:22 AM »
There are lone pairs of e- in graphite which are mobile and thus can conduct electricity. But in my textbook, graphite is an "exception" in electricity conductivity. In cases of simple covalent molecule, the lone pair electrons are actually not mobile. May I know the rationale behind this?

There is no lone pairs in graphite - there are only pi-bonds.

What do you know about electron delocalization?
