I got two postive values.
Yeah for the Ecell one was definitely negative and one was positive
so for hcl on the frq. I put h-bonding, dipole dipole and van der waals. I forgot that cl wouldn’t hydrogen bond, so would i still get points for putting the two right answers?
lol I did the same tobster18 I was so upset
Same @Tobster18 I am so so triggered rn
ughh @Tobster18 im mad rn
i hope they won’t take off a point for including extra things, but they probably will… but why doesn’t HCl hydrogen bond? i’m confused but it’s over anyway so
my first ap test scarred me yall… im feeling so mad cause i probably could’ve killed it had i studied buffers, formal charge, and chromatography… lost like 13 points off my frq for sure.
@kylxxx
The only elements that form hydrogen bonds are fluorine, oxygen, and nitrogen
@kylxx The electronegativity difference between H and Cl is not quite large enough to form a very strong net dipole that would attract the positive and negative partial charges of other surrounding molecules… Cl is larger than F, for example, so the Coulombic attractions between it and H would be weaker (the strength of the attractions is indirectly proportional to the square of distance)
I didn’t answer the last question and the first half of the 6th question. lol I am pretty sure it was that HNO2 and NaNO2 will make good buffers because of the common ion effect right?
@logosoverpathosm HCl is still polar enough to create dipole dipole attraction between other HCl molecules

@gkdudtlffj of course; but we are talking about a special subset of dipole-dipole interactions, Hydrogen bonding.
wait so are the free response questions going to be released to the public tomorrow morning? or just to teachers?
@avogardo To the public. Also do you guys think the 2017 exam was harder than the 2016 exam? Or easier than 2014/2015?
@gkdudtlffj For me, personally, this exam was harder than the ones for 14/15/16… Most people I’ve talked to have shared a similar sentiment, but it could just be a matter of the luck of the draw of the topic distributions… So really hard to say how the cutoff will be based on that 
But I’ve heard from those that had alternate forms that forms E and Q were much easier, or rather covered what are typically considered “simpler” topics. The cutoff will be the same for all, however…
@logosoverpathosm
the 2014,2015 and 2016 frqs were easy. Finished them under timed conditions and still had time to spare. However the 2017 exam wasnt as easy. It was mostly concept.
@waterbrether725 I would definitely agree. I had the same experience with 14/15/16 and was thus quite confident going into the test, but I was in for a surprise
Any score predictions?
