=== > NOCl2 <=== new formula based on the explanation below, therefore Degree of unsaturation
===> (1/2 x 2) + 2 - 2 = 2
2

[FONT=Arial, Helvetica, sans-serif]Degrees of Unsaturation = 2 (i think).​

" (5) Calculate the degrees of unsaturation in your formula. You may have too

few (fewer than zero, i.e. a negative number) or too many degrees of
unsaturation in your compound. (Too few degrees of unsaturation means
that you have too many H atoms.)
(a) If you have too few number of degrees of unsaturation, you must add
degrees of unsaturation, i.e. remove H’s without changing the molecular
weight. There are a few ways to do this. (1) Replace CH4 with O. This has
the effect of adding one degree of unsaturation. (2) Replace C2H4 with N2.
This also has the effect of adding one degree of unsaturation. (3) Replace
H16 with O. This has the effect of adding eight degrees of unsaturation."
