<p>Look at the solution for 5d!!! It shows Xenon single bonded to the three oxygen molecules! However the most stable structure for XeO3 is Xenon double bonded to them, because the formal charge on each atom is zero! The college board solution is wrong according to Wikipedia! Xenon</a> trioxide - Wikipedia, the free encyclopedia</p>

<p>Would I lose points for drawing the correct Lewis structure on the AP Exam???</p>

<p>any idea how college board could be this wrong?</p>

<p>uh, bump? seriously, this is ridiculous if they don’t accept the right answer. it’s clearly obvious that the double bond structure is the more viable, and wikipedia confirms, so why would they use the single bond structure? would i get graded down for being right?</p>

<p>yeah, they are wrong, xenon trioxide does have double bonds, making the formal charge 0.</p>

<p>I am unsure why they would have single bonds, as this is not the lewis structure for xenon trioxide</p>

<p>Well I’m sure they either omitted the question or gave credit for either answer. They would never allow anything that egregious to pass.</p>
