FRQ for AP Chem. 2009 Debate

<p>I am pretty sure that S is more attracted to the magnet than S-2 because it has 2 unpaired electrons.</p>

<p>for number 3 part e
i got first order to CH4
and 1/2 order to Cl2</p>

<p>Oh yeah, forgot the C in the equation, but I got it right on the test :P</p>

<p>I got 1/2 order to Cl2 as well.</p>

<p>Questions are up:

<p>for 6c) i put P and S orbitals, because the hybridization of S is sp. Am I right or wrong?</p>

<p>I think I just put p orbital.</p>

<p>i’m pretty sure it’s p just because it’s the outer most orbitals and in the p orbital there are empty slots for a lack of a better term</p>

<p>I put s and p as well, due to the sp hybridization. idk though, there are 2 lone pairs in H2S, if that means anything.</p>

<p>what about my math and all of that for my other questions?</p>

<p>I am so glad I didn’t take AP chem. Ew.</p>

<p>

OMG. We never learned a thing about magnets all year, so I randomly put down “It is paramagnetic.” because I heard the term somewhere. Is that actually right?</p>

<p>yeah, paramagnetism was right lol</p>

<p>IHEARTAPCHEM, I glanced over your math and it all looked similar to what I got. But for the orbital question, it asks what orbitals are involved, and since the hybridization is sp, both s and p orbitals are involved. I am pretty sure that is right, but if anyone has a better explanation as to why its not both s and p, let me know.</p>

<p>hydrogen bonding is separate from dipole dipole</p>

<p>i believe it was H2S for both parts of (d)…</p>

<p>otherwise i got WRECKED… hope for a 50% overall in the FR…</p>

<p>^ I don’t believe so.</p>

<p>H2S has stronger London dispersion forces because it has more electrons.</p>

<p>H2O has stronger dipole-dipole forces because O is more electronegative than S and hence draws electrons away from H moreso than S. Note that the hydrogen bonding present has nothing to do with dipole-dipole forces.</p>

<p>^ i completely agree 100%</p>

<p>Are the FR’s posted somewhere? Or did your chemistry teacher give them back?</p>

<p>Also, I put s and p orbitals because it exhibited sp hybridization.</p>

<p>same thing, bigb</p>

<p>hey guys: URGENT QUESTION.</p>

<p>FORM B FR is posted already?!?!?!
Won’t we all be put at a disadvantage, since people who take form B will be taking it on around… may 20th?</p>

<p>I recall that my school only administered one form of the exam, so could this form b really be the form b questions that they will take on may 20th?</p>

<p>surely collegeboard can’t be that stupid…</p>

<p>^ Form B is for internationals
the make up test is different</p>

<p>why doesn’t hydrogen bonding explain why H2O has stronger dipole? Hydrogen bonding is a strong form of dipole force</p>
