What does the Lewis Dot Diagram for PBrF4 look like? (phosphorous bromine tetrafluoride - I think thats what it's called)

Re: chem

K that's what I figured. But is the molecule polar? All the bonds are polar (En difference greater than or equal to 0.4). But does the fact that the Br is different that the 4 fluorides make it a difference enough to make it polar? If all 5 were fluorides, it obviously wouln't be polar.

En of P = 2.19
En of F = 3.98
En of Br = 2.96

i am NOT the authority on this, but i'd say it is. If you think about it:
You have this lonely Br atom on one end, which isn't all that EN, then these four MONSTERS of EN-ity on the other side, who pull like some crazy mofo's on those e-'s?

anyway, ask someone who knows their stuff, it's been 2 1/2 years for me.. i can tell you all about silicon crystals though.. if you care to know

gibberish.... LOL


god i hate chemistry

Yes it is polar, when thinking about polarity, think vectors.

Edit: sorry i didn't pay attention to the whole molecule . So yeah it will because, there are 4 fluorines (most electronegative F = 4.0) while bromine is less electronegative. The fluorines will pull electrons towards themselves from other atoms, making P and ultimately Br (which are both less electronegative) slightly more positive, giving a small charge separation.

but the other atoms are Fluorine, which is even more EN.

Looks polar to me, although Chem was a looooong time ago.

hehe [from the religion thread] since we all believe it's polar, it has to be ;P

lol...in a parallel universe it might not be

imagine the consequences...like hmmmm...tiesto spinning scooter (even though he's pretty close to that stage..

I think scooter wouldn't be half-bad if they fot rid of this blonde idiot that is too full of himself.. take out HIS voice from all tracks and some of them would be fun

yeah true...those lyrics sounds like as if they've been written by a crackhead.

Ok I need your help on this big time... simple question tho. Do any of the following have resonant structures?:

PO3 3-
PO4 3-
BrO2 -
BrO3 -

I drew the structures for each and none turned out to be resonant, but the question asks "draw all resonant structures for those that apply". So I'm thinking at least one of them should have been.
