Explanation:i think
This is what I got hope it helps
Event 1 is an example of a chemical reaction.
<u>Explanation:</u>
Whenever there is a chemical reaction, we can find that by means of a color change, formation of any gas, vapors, bubbles or any color or colorless precipitation, or by means of heat generation.
In the event 1 there is only a clear liquid in the beaker again it is added to a clear liquid in another beaker, forming an orange colored liquid , which shows that there is an occurrence of some chemical reaction.
So Event 1 is most likely an example of a chemical reaction.
Mass spectrum of Dodecane will give following information.
1 ) Molecular Peak or Parent Peak:
The Parent peak will appear at m/z = 170. The intensity of this peak will be very weak.
2) Fragments:
Usually the fragments of such long chain alkanes appear with spacing of 14 amu, Hence, the peaks in dodecane will be as follow,
170 - 156 - 142 - 128 - 114 - 100 - 86 - 72 - 58 - 44 - 30 - 16
3) Base Peak:
Most probably the Base peak will appear at m/z = 57. This peak is due to the formation of tertiary butyl cation as the intensity mainly depends upon the stability of cation. So this cation might form due to rearrangment giving the intensity of 100%.
