What is even electron rule?
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.
Also, what is the rule of 13? The rule of 13 states that the formula of a compound is a multiple n of 13 (the molar mass of CH ) plus a remainder r .
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.
What is meant by McLafferty rearrangement?
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.
