Question

The degree of unsaturation (Double Bond Equivalent) for an organic compound with the molecular formula $C_{10}H_{7}Cl_2N$ is:

Prashant Kotian · Accepted Answer

Correct answer: C. Using the formula DBE = C + 1 - (H + X - N)/2, where C=10, H=7, X=2, N=1. DBE = 10 + 1 - (7 + 2 - 1)/2 = 11 - 8/2 = 11 - 4 = 7.
