Question

Calculate the degree of unsaturation (or IHD, Index of Hydrogen Deficiency) for C8H12.

Answer 1

Answer:

4.

Explanation:

Hello,

In this case, for the calculation of the degree of unsaturation, we apply the following formula:

$Degree\ of \ insaturation=C-\frac{H}{2}$

Thus, since we have eight carbon atoms and twelve hydrogen atoms, it turns out:

$Degree\ of \ insaturation=8-\frac{12}{2}=8-6=4$

It means that four substituents are missing in order saturate the molecule.

Regards.
