Give the splitting pattern expected for the indicated H-NMR signal.

could you help me out with these question and explain to me step by step thanks

Match the following molecules with their infrared spectrum on the next two pages by placing the answer on the provided lines. There are more molecules (six) than spectra (four).

Show how the NMR spectrum of 2-bromo-2-methylbutane would look like, include approximate chemical shifts, integration ratios, and signal multiplicity. Briefly state your reasoning so i can understand better, thanks!

Please help answering all parts of the following question...thank you! From the following sets of data, please propose a reasonable structure for the unknown organic compound. This molecule is entirely composed of C, H, and N only. Please show all of your work and feel free to write on the spectra any clues as to the structure.

I  need explanation .The following spectrum is of a haloalkane. Identify the halogen and suggest a possible alkyl group. Fully explain your answer, making reference to both molecular and fragment ions.Note that the two peaks with highest m/z values occur at 108 and 110, with the peak at m/z 110 having an intensity of approximately 95% of that at m/z 108. and the answer is : i need explanation  It is the spectrum of ethyl bromideFormula: C2H5BrMolecular weight: 108.965 g/molPeaks with an m/z of 108 and 110 correspond to [C2H579Br]+ and [C2H581Br]+

Please help, am using old tests to study for MCAT and i need help with this question! Which compounds (from the picture attached) corresponds to the 4H NMR in the image attached.  Annotate the spectra with any and all relevant signals that demonstrate the relationship and support your answer choice.Explain the meaning behind your annotations and how they correspond to the structure you choose. thanks in advance
