6th edition 4.23

Postby Andrea- 3J » Thu Nov 29, 2018 8:33 pm

It says to find the lewis structure and predict the shape of OSCl3, SO2Cl2, and IO2F2-.
For OSCl3 the molecular formula is AX4N0 which is a tetrahedral. Did I write the molecular formula correctly?

For SO2Cl2 the molecular formula is AX4N0 which is also a tetrahedral.

For IO2F2- the molecular formula is AX4N1 which is a trigonal bipyramidal, seesaw. Did the I write the molecular formula correctly?

Yes you did but it's not the molecular formula but VSEPR formula.

I also had a question on this problem. On the Lewis structures for part b and c, why is there not a double bond for the oxygens?

There is a double bond for both the oxygen atoms in B, but only one has a double bond in letter C because an O atom with a single bond and 3 lone pairs has a formal charge of -1 and the overall molecule has a negetive 1 charge.
