Well all reactions need energy to start it. The light is the energy that the reaction requires to start it. Sunlight also has no mass in the first place so laws of conservation of mass don't apply to it.
Answer:
See figure 1
Explanation:
We have to remember that in the isomer structures we have to <u>change the structure</u> but we have to maintain the <u>same formula</u>, in this case
.
In the formula, we have 1 nitrogen atom. Therefore we will have as a main functional group the <u>amine group</u>.
In the amines, we have different types of amines. Depending on the number of carbons bonded to the "N" atom. In the <em>primary amines</em>, we have only 1 C-H. In the <em>secondary amines</em>, we have two C-N bonds and in the <em>tertiary amines</em>, we have three C-N bonds.
With this in mind, we can have:
-) <u>Primary amines:</u>
1) n-butyl amine
2) sec-butyl amine including 2 optical isomers
3) isobutyl amine
4) tert-butyl amine
-) <u>Secondary amines:</u>
5) N-methyl n-propyl amine
6) N-methyl isopropyl amine
7) N, N-diethyl amine
-) <u>Tertiary amines:</u>
8) N-ethyl N, N-dimethyl amine

I hope it helps!
