QR

If three coins are flipped, which of the folowing is the probability that all three faces will be heads?

3/8
1/6
1/4
1/3
1/2

Ochem #99.. the synthesis of antispasmodic spasmolytol..
anybody know how to do this one?

Also, for #97 isn't the answer A.constitutional isomers not D.identical?

I have found some errors in ochem section like #72, and found the qr section is way too hard. I was wondering if this is a good representation of the real thing. If if is, :scared:!!!!!

Yeah 97 has to be an error, I got A

For 99 IMO has to be A or D and not C. You have to have the Br's on the ring initially.

for the QR question: Answer is 1/8. In my packet the ADA released a corrections sheet. Choice A should be 1/8 not 3/8

Take a look at my other post on this board about this test. Let me know if you can help me out.

they probably do the same thing on the real dat-

grade you wrong for correct answers, and then 4 years later realize that it was THEIR mistake...
