How many electrons should `X_(2)H_(4)` liberate so that in the new compound X shows oxidation number of `-1//2`(E.N. X gt H)

Explanation

To solve the problem, we need to determine how many electrons the compound \(X_2H_4\) must liberate for the element \(X\) to achieve an oxidation state of \(-\frac{1}{2}\).

### Step-by-Step Solution:

1. **Identify the Oxidation States:**
- In the compound \(X_2H_4\), we need to find the oxidation state of \(X\).
- The oxidation state of hydrogen (H) is \(+1\).
- The total contribution of hydrogen in \(X_2H_4\) is \(4 \times (+1) = +4\).
