For compound having the formula `GaAlCl_4`the correct option from the following is

Answer

To solve the question regarding the compound with the formula `GaAlCl_4`, we will analyze the components and their properties step by step.

### Step 1: Identify the components of the compound
The compound `GaAlCl_4` consists of gallium (Ga), aluminum (Al), and chlorine (Cl).

### Step 2: Determine the oxidation states
In this compound, aluminum typically has an oxidation state of +3. Since there are four chloride ions (Cl^-), which each have a -1 charge, the total negative charge contributed by chlorine is -4. To balance this, gallium must have a +1 oxidation state. Thus, we can summarize:
- Al: +3
- Ga: +1
- Cl: -1 (for each Cl)

### Step 3: Analyze the coordination
In the compound `GaAlCl_4`, gallium is not coordinated with chlorine directly. Instead, aluminum is the central atom, and the chloride ions act as ligands that coordinate with aluminum. Gallium acts as a counter ion.

### Step 4: Compare electronegativity
Gallium (Ga) is more electronegative than aluminum (Al) due to its smaller atomic radius and the presence of d-orbitals, which leads to less shielding effect. This means that gallium has a higher ability to attract electrons compared to aluminum.

### Step 5: Conclusion
From the analysis, we can conclude that:
- Gallium is not coordinated with Cl; it acts as a counter ion.
- Chlorine forms bonds with aluminum, not gallium.
- Gallium is indeed more electronegative than aluminum and is present as a cationic part of the salt.

Thus, the correct option is that gallium is more electronegative than aluminum and is present as a cationic part of the salt.

### Final Answer:
The correct option is: Gallium is more electronegative than Aluminum and is present as a cationic part of the salt.
