Why is benzene diazonium chloride not stored and is used immediately after its preparation?

Explanation

**Step-by-Step Solution:**

1. **Understanding Benzene Diazonium Chloride**: Benzene diazonium chloride is a chemical compound with the formula C6H5N2Cl. It is formed by the reaction of aniline (C6H5NH2) with nitrous acid (HNO2) at low temperatures.

2. **Stability of Benzene Diazonium Chloride**: This compound is known to be unstable. The diazonium group (N2^+) is particularly prone to decomposition.

3. **Decomposition Process**: When benzene diazonium chloride is stored for a long time, it tends to decompose. The unstable diazonium group can break down into nitrogen gas (N2) and a phenyl radical (C6H5·). This reaction can be represented as:
