What is even electron rule?

The even electron rule states that ions with an even number of electrons (cations but not radical ions) tend to form even-electron fragment ions and odd-electron ions (radical ions) form odd-electron ions or even-electron ions.
Herein, what is Stevenson rule?
Stevenson's rule. Rule stating that in competing fragmentations the product ion formed from its neutral species counterpart with the lower ionization energy will usually be the more abundant.
Considering this, what is an M 1 peak?
If you had a complete (rather than a simplified) mass spectrum, you will find a small line 1 m/z unit to the right of the main molecular ion peak. This small peak is called the M+1 peak.
The McLafferty rearrangement is an organic reaction seen in mass spectrometry. The McLafferty rearrangement is an example of a hydrogen atom jumping to the other fragment as a part of the process of the bond breaking. It happens in an organic molecule containing a keto-group.
