i need help. can you please explain and
show the math too thanks!
Difference in peak positions = 9 - 5 = 4 ppm
Hz = ppm x Frequency of instrument (MHz)
So, the two peaks are separated by = 4 ppm x 200 MHz = 800
i need help. can you please explain and show the math too thanks! Question 8 [1.5...
Question 10 [1.2 pts] A certain compound was analyzed using a 400 MHz NMR spectrometer. The resulting spectrum exhibits a singlet at 4.5 ppm and a singlet at 7.5 ppm. What numerical value (expressed as a whole number) correctly completes the following statement. The two singlets are separated by __ Hz.
ASAP need help with 1 to 10 please and thank you
1. Multiple choice questions (20) 1.Which of the followings is the most reactive one in electrophilic aromatic substitution? NO; D. A. B 2. If a proton resonance at 200 MHz in a spectrometer with a magnetic field of 4.7 T, what will be its resonance frequency in a spectrometer with a magnetic field of 9.4 T?

Can you please dumb this down and do it step by step closely
with full explanation? I have the simple walkthrough already but
it's not helping much!
Thanks so much in advance!

Hello! I need some help on both of these NMR questions please.
Thanks!
1. Below is shown the spectra of CH40, with a mass of around 68amu (rounded). What is the structure of it based on the following information: T PPM 1 180 120 100 PPM BO 66 46 zb 200 ido Top-graph is the proton-spectra and bottom graph is the carbon-spectra. The proton peaks are both singlets, yet one is 3 times larger than another: this is a big...
NMR Aa7 If you can, please provide the answer in this sheet. Otherwise, do draw the structure and schematic analysis carefully and clearly, in a plain sheet. DONT USE PENCIL Aal: The full spectrum of an unknown compound is displayed in bottom. The spectrum is also blown up to afford the dose-up of peaks. There are numerical values in red beneath some of peak sets. They are proton integration number. With the detailed spectral information and the molecular structures provided....

Given this IR Spectra of an unknown compound, how do I
determine the structure of what I have?
I think I have some sort of ketone? Possibly a methyl
ketone.
Attached is also the H-NMR. Please help determine structure of
unknown.
the
only other information i have is that it has a low molecular weight
and is neutral

Please help. I need a step by step solution to find the
compound. I'm not too confident with what m/z means and how to read
the IR graph yet. What does quin (5) have to do with 2.36 ppm in
the H NMR? A description about those would be great too. Thank you
so much.

Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...
