Question 207
It was asking about which of graph is the NMR spectra for
CH3OC(CH3)3.
The key is A(the one 3 is down field). I chose B(the one 9 is down field). Oxygen is electron donating. The 9 hydrogen on
-C(CH3) is further from the oxygen atom. Hence have less electron on them, and then down field. I just don't get it how could the key be A. Could someone tell me what I am missing here.
Question 190
It was asking which change would not interfere with the repeated transmission of an impuse.
The key is C. I chose A(add cholinesterase blocker). I don't understand how could it be A.
Thanks a lot
