Question

Find the degrees of unsaturation in C₈H₅NO.
a) 4
b) 5
c) 6
d) 7

Answer 1

The degrees of unsaturation in C₈H₅NO is 4.

Step-by-step explanation:

The degrees of unsaturation in C₈H₅NO can be calculated using the formula:

Degrees of unsaturation = (2C + 2 + N - H - (X/2))/2

Where C is the number of carbon atoms, N is the number of nitrogen atoms, H is the number of hydrogen atoms, and X is the number of halogen or halogen-equivalent atoms.

In the case of C₈H₅NO, we have 8 carbon atoms (C), 1 nitrogen atom (N), 5 hydrogen atoms (H), and no halogen atoms (X). Plugging these values into the formula, we get:

Degrees of unsaturation = (2(8) + 2 + 1 - 5 - (0/2))/2 = 4

Therefore, the correct answer is 4 (a).
