Formal Charges: Please help me
« on: February 13, 2011, 01:15:59 PM »
why cant i get -1?

tinypic.com/view.php?pic=14buuti&s=7

ok in class we did this.
and for O FC= 6-4-3=+1
but S FC = -1 (I get 6-4-1= +1) which is wrong. what am i doing wrong?

i solve by doing: group # - total (bonds and lone pairs(each = 1)) - lone pairs (each pair = 1)
please tell me what im doing wrong i have a test soon.

I'm somewhat confused. The answer for O should be -1 and that for S +1.

What did your teacher say was the correct answer? Are you sure you copied the correct molecule?
