Which of the following statements corresponds to the nitrogen rule of mass spectrometry?
Select one:
a. Molecules with odd numbers of nitrogens will have an even-numbered molecular weight.
b. Molecules with even numbers of nitrogens will have a molecular ion that is two units less than the molecular weight.
c. Molecules with odd numbers of nitrogens will have an odd-numbered molecular weight.
d. Molecules with even numbers of nitrogens will have a molecular ion that is two units more than the molecular weight
Homework Answers
The nitrogen rule important in determining the nitrogen content.Nitrogen rule: If a compound has even number (or 0) of nitrogen atoms, the molecular ion peak will appear at even mass number and if a compound contains odd number of nitrogen atoms then molecular peak will be at odd mass value.
So option C is correct. A is false as odd -even relation is given. B and D does not fit into the rule.

In Mass Spectrometry (MS) the molar mass of compounds can be determined. The so-called "molecular ion" corresponds to the molecular mass when Electron Impact Mass Spectrometry (EIMS, one of several common MS techniques) is used. It is important to realize, though, that the mass detected by MS depends on the isotopes present in the molecule. The questions below try illustrate the impact of isotope distribution in a molecule. What is the molar mass of the compound shown below? What is...

3. Which of the following statements best explains why nitrogen gas at STP is less dense than Xe Has at STP? a) Because Xe is a noble gas, there is less tendency for the Xe atoms to repel one another, so they pack more densely in the gas state. b) Xe atoms have a higher mass than N2 molecules, Because both gases at STP have the same number of molecules per unit volume, the Xe gas must be denser, c)...

Which of the following statements is incorrect regarding the decision rule for ARR? Select one: a. The decision rule for ARR varies among entities. b. Only investments with an ARR higher than the RRR should be considered. c. Generally, the investment with the highest ARR is to be accepted. d. Only investments with an ARR equal to the RRR should be considered.

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!!!
