Yes I got a reply. My teacher spoke to a grader and I received a reply.
It was a mistype and the most likely course of action will be a different scale of grading for the groups who had it and the groups who didn’t. We will found out based on our scores, I guess. The questions did exist; some just did not have it.
A professor on twitter sent a message to the AP guy and asked the same thing. Such a boost of confidence, lol.
@cocolover123 yes!!!
Was it just 2e) that was missing?
It was 2e, 2f, and 3f (possibly. I think i remember 3f but I’m not really sure). I know for a fact I didn’t have 2f or 2e
^^ yes!
and hahahah yeah I am so happy that all is well 
Our scores shouldn’t be impacted and it will come out to be fair for us all. I hope we all passed with 4’s and 5’s!!
@cocolover123 Do u mind linking the tweet? I dont wanna sound rude, just curious
@Newdle An opinion was asked, and an opinion was offered. One can choose to agree/disagree with said opinion. Ask your chem teacher what s/he thinks. None of us will know for sure until the scoring standards come out.
@pillowspillows I’ll PM you it, one second. It involves my twitter account and I don’t really want to show that off to everyone here.
@skieurope when do the scoring standards usually come out? is it like in late june or possibly earlier?
@pillowspillows Late July/Early August
The only thing I have seen that could serve as a precedent for CB accepting a range of values for the angle would be the AP Chemistry Practice Exam and Notes that was released to teachers for the purpose of giving teachers an idea of what the revised curriculum would look like starting in 2014. One of the problems asked for the angle for the H-C-N bonds in Methanamide (CH3NO).

It is pretty clearly 120 degrees as C is sp2 hybridized and has a trigonal planar geometry. The grading scale says "Accept 120° ± 10° for the angle (i.e., 110° ≤ x ≤ 130°.) "
Obviously, as @skieurope says, we will not know until the scoring guidelines are released. Just thought I’d share what I had came across earlier.
Hey guys so I probably got like a 32/46 on frq which is like a 70%, so what is the maximum amount of questions I can miss on the mc to get a 5? Also, for frq, what if we get one sig fig wrong? Is the entire answer wrong?
@Messi4lyfe Well last year’s curve was a 72%, so with a 70% on FRQ you could get a 38/50 on MC and still get a 5.
Also, will 105 degrees instead of 104.5 degrees work too?
@messi4lyfe I think you can miss up to 10 multiple choice and still get a 5. The cut off for a 5 last year was a 72. There was 60 questions on the mc part of the exam, but 10 were experimental. So you can technically get more than 10 wrong and still get a 5, if you got some experimentals wrong.
And for 6b, was it necessary to write the equilibrium, or will just an arrow also be accepted? I don’t remember if I put equilibrium or not 
@ninjadu do you need to earn 72 points? or just get 72% of the exam correct?
@zach1198 I heard that this years curve was 75%, but im not sure. Is that true?
I don’t understand the grading because this was the first AP I took. Let’s say hypothetically I get 50/50 on multiple choice and 0/50 on frq. Would my raw score be 50/100 (just adding the two scores) or 25/100 (taking the average of both scores)
@c0llegeb0und2468 average of 100% and 0% is 50%, which is 50/100 not 25/100
