Give the order of `(a)` nucleophilicity `(b)` basic character, and `(c)` fugacity of the following :
(i) `F^(Ө)`
(ii) `Cl^(Ө)`
(iii) `Br^(Ө)`
(iv) `I^(Ө)`.

Explanation

To determine the order of nucleophilicity, basic character, and fugacity for the ions \( F^- \), \( Cl^- \), \( Br^- \), and \( I^- \), we can analyze each property step by step.

### Step 1: Nucleophilicity
Nucleophilicity refers to the ability of a species to donate a pair of electrons. In this case, we are looking at the halide ions.

1. **Size and Charge Distribution**: As we move from \( F^- \) to \( I^- \), the size of the ions increases. Larger ions have more dispersed negative charge, which reduces ion pairing and increases nucleophilicity.
2. **Order of Nucleophilicity**: Therefore, the order of nucleophilicity is:
