M+ is normally the one all the way to the right. Beware sometimes it may be so small you can not even see it. Actually this was the case for one on my test today. I had to draw out the spectrum from hand. What a nightmare! =]]

is this peak always the one furthest to the right or the one with the highest m/z?

Because it M+ give your the exact molecular weight of the unknown molecule you are trying to figure out. So it will not take into affect the lose of any electron. The molecule you determine you have should be the molecular weight equal to the value of the M+ peak on the graph. I hope that makes scene and is right. =]]

If the M+ peak is the furthest to the right, how do you know if it is the M+ peak or the M+1 peak?

Thank you very much for your videos. I got a 4.0 in O chem 1 last quarter, and I think you are part of the reason that happened! I’m taking o chem 2 right now, and will definitely be watching your videos again. Thanks again for your time and hard work.
