Hey guys a few more questions on Ochem help from various sources:
The answer is all of these structures but I dont understand why the nitrile (far right), has only 1 peak? Won't it show 1 and 4 peaks?
Answer: Ca(s) + C(graphite) + 3/2 O2 (g) -> CaCO3 (s)
Can someone explain what to do for these types of questions? I don't know what its asking and don't recall Chad covering it.
The answer is 8 and I marked the ones I thought are centers - my question is are these the right chiral centers? (the one marked in green is the one I am not sure about).
Thnx
Question 1 said:So this one, the question is: Which of the compounds shown below will show only one resonance peak in its H NMR spectrum?

Question 2 said:The heat of formation reaction for solid CaCO3 is:
Answer: Ca(s) + C(graphite) + 3/2 O2 (g) -> CaCO3 (s)

Question 3 said:How many chiral centers are in compound below?
The answer is 8 and I marked the ones I thought are centers - my question is are these the right chiral centers? (the one marked in green is the one I am not sure about).
