Question

The degree of unsaturation, or index of hydrogen deficiency, is the number of pi bonds plus rings in a molecule. Specify the degree of unsaturation (index of hydrogen deficiency) of the following formulas: (a) C24H30 (b) C6H7BrCl2 (c) C5H6N2O2

Answer 1

the degree of unsaturation for C5H6N2O2 is 9.5.

Step-by-step explanation:

To determine the degree of unsaturation (index of hydrogen deficiency) of a molecule, we need to calculate the number of pi bonds and rings present.

(a) C24H30:

To calculate the degree of unsaturation, we can use the formula: Degree of unsaturation = (2n + 2) - (H + X)/2

For C24H30:

Degree of unsaturation = (2 * 24 + 2) - (30 + 0)/2

= 50 - 15

= 35

Therefore, the degree of unsaturation for C24H30 is 35.

(b) C6H7BrCl2:

Degree of unsaturation = (2 * 6 + 2) - (7 + 2 + 2)/2

= 14 - 11/2

= 14 - 5.5

= 8.5

Therefore, the degree of unsaturation for C6H7BrCl2 is 8.5.

(c) C5H6N2O2:

Degree of unsaturation = (2 * 5 + 2) - (6 + 2 + 2)/2

= 12 - 5/2

= 12 - 2.5

= 9.5

Therefore, the degree of unsaturation for C5H6N2O2 is 9.5.
