Question

This is for my mass spectrometry lab report.

I have to figure out the m/z of the base peak and in order to do so I need to know where the weakest bond is for each compound so I can split them up.

Please do that for me for each of the compound. I just want to double check my work.

I’ve attached on the second picture an example of one of the compound.

Thank you ahead of time!!!

Step 1: Calculate the molecular weight of all of the compounds below. This number gives you the molecular ion peak on the mass spectrum. Remember, the molecular ion peak is formed when a molecule just loses one electron. Write the mass/charge ratios of all of the molecular ion peaks underneath each compound. If the molecular ion peak consists of isotopes, you must write down both numbers! Only"C isotopes do not have to be written down. butyl ether 3,3-dimethyl-1-hexene Molecular lon Frngment30 ealerale on Pra12 pentyibenzene 1-chlorooctane 14147, Molecular lon Fragment1H8 Molecular lon Fragme1 Br 3-methyl-1-hexanol 1-bromo-4-methylpentane Molecular lon Fragment Molecular Ion Fragment Step 2: Look at the mass spectra and see if any of the molecular ion peaks are observed. Be careful Some compounds might have the same molecular ion peaks or fragments that match the molecular ion peaks of other compounds. Realize, in some cases, the molecular ion peak may not be observed! Step 3: Look for other obvious patterns. What do I mean? Do remember our discussion about isotope peaks? What atoms have distinct isotope patterns? Look for them. Step 4: After steps 1-3, look at the base peaks or other fragments that might give the compounds identity away.
