Answer:
4.
Explanation:
Hello,
In this case, for the calculation of the degree of unsaturation, we apply the following formula:
[tex]Degree\ of \ insaturation=C-\frac{H}{2}[/tex]
Thus, since we have eight carbon atoms and twelve hydrogen atoms, it turns out:
[tex]Degree\ of \ insaturation=8-\frac{12}{2}=8-6=4[/tex]
It means that four substituents are missing in order saturate the molecule.
Regards.
