Mgcl2 Polarity
« on: November 04, 2019, 06:03:13 PM »
Can someone show me why mgcl2 is polar? I dont see how it is as the forces cancel out. Please prove this without using electroneg.


CL-Mg-Cl
the arrows come out of mg
and cancel out

THANKS!

MgCl2 has an ionic structure and this molecular formula does not make sense.

Could MgCl2 possibly be gaseous in the question? It's not the usual state (bp 1 412 °C) so the assignment should necessarily mention it.

It's the only situation where I detect a sense in the assignment. As a solid or solution it's just meaningless.

With an angle in a Cl-Mg-Cl gaseous molecule (IF it vaporizes as triatomic molecules) it would be polar, just like H2O is. With 180°, no chance indeed.
