Explanation:

Step1: Recall the formula for elements of unsaturation

The formula for elements of unsaturation (EU) is \( EU=\frac{2C + 2+N - H - X}{2}\), 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 atoms. In the formula \(C_8H_4N_2\), \(X = 0\).

Step2: Substitute values into the formula

Substitute \(C = 8\), \(N=2\), \(H = 4\), and \(X = 0\) into the formula:
