For cis platin which option is incorrect ?

Options

A. It is used for cancer treatment
B. EAN is 86
C. Hybridisation is `dsp^(2)`
D. its dipole moment `ne0`

Explanation

To determine which option regarding cisplatin is incorrect, we will analyze the properties of cisplatin step by step.

### Step 1: Identify the Chemical Formula of Cisplatin
Cisplatin is a coordination compound with the formula **cis-[PtCl2(NH3)2]**. This indicates that it contains platinum (Pt) as the central metal atom, two chloride ions (Cl⁻), and two ammonia molecules (NH₃) as ligands.

**Hint:** Remember that the prefix "cis" indicates that the similar ligands are on the same side of the central metal atom.

### Step 2: Determine the Oxidation State of Platinum
To find the oxidation state of platinum in cisplatin, we can set up the equation based on the charges of the ligands:
- The charge of each chloride ion (Cl⁻) is -1, and there are two chloride ions, contributing a total of -2.
- Ammonia (NH₃) is a neutral ligand and contributes 0 to the charge.

Let the oxidation state of platinum be \( x \):
\[ x + (-2) + 0 = 0 \]
Thus, \( x = +2 \).

**Hint:** The oxidation state can be calculated by balancing the charges from the ligands with the overall charge of the complex.

### Step 3: Write the Electronic Configuration of Platinum
The atomic number of platinum (Pt) is 78. The electronic configuration of neutral platinum is:
\[ [Xe] 4f^{14} 5d^9 6s^1 \]

When platinum is in the +2 oxidation state, it loses two electrons (one from the 6s and one from the 5d subshell):
\[ [Xe] 4f^{14} 5d^8 \]

**Hint:** Remember that the electronic configuration changes when the metal ion loses electrons during oxidation.

### Step 4: Determine the Hybridization of Cisplatin
Cisplatin has a coordination number of 4, as it is surrounded by four ligands (two Cl⁻ and two NH₃). The hybridization can be determined as follows:
- For a coordination number of 4 and a square planar geometry, the hybridization is **dsp²**.

**Hint:** The hybridization can be inferred from the coordination number and the geometry of the complex.

### Step 5: Analyze the Dipole Moment
Cisplatin has a square planar geometry with the two chloride ions and two ammonia molecules positioned adjacent to each other. In this arrangement, the dipoles from the Cl⁻ ligands do not cancel out, resulting in a non-zero dipole moment.

**Hint:** The geometry of the complex affects the dipole moment; in cis configurations, dipoles may not cancel.

### Step 6: Calculate the Effective Atomic Number (EAN)
The Effective Atomic Number (EAN) can be calculated using the formula:
\[ \text{EAN} = Z - \text{oxidation state} + 2 \times \text{coordination number} \]
Where:
- \( Z \) = Atomic number of Pt = 78
- Oxidation state = +2
- Coordination number = 4

Substituting the values:
\[ \text{EAN} = 78 - 2 + 2 \times 4 = 78 - 2 + 8 = 84 \]

**Hint:** EAN is a useful concept to determine the stability and electronic configuration of coordination compounds.

### Conclusion
Based on the analysis:
- The incorrect statement regarding cisplatin is that its EAN is 86. The correct EAN is 84.

**Final Answer:** The incorrect option is that the EAN of cisplatin is 86.
