Consider the following statements.
I.Polydentate ligands are not listed in alphabetical order.
II.In casse of abbreviated ligand, the first letter of the abbreviation is used to determine the position of the ligand in the alphabetical order.
The correct option is

Options

A. Only I
B. Only II
C. I and II
D. Neither I nor II

Answer

To analyze the statements given in the question, we will evaluate each statement one by one.

### Step 1: Evaluate Statement I
**Statement I:** "Polydentate ligands are not listed in alphabetical order."

- **Explanation:** Polydentate ligands are ligands that can bind to a metal ion at multiple sites. When naming coordination compounds, all ligands, including polydentate ligands, are listed in alphabetical order based on their names, irrespective of whether they are polydentate or monodentate. Therefore, this statement is **false**.

### Step 2: Evaluate Statement II
**Statement II:** "In case of abbreviated ligands, the first letter of the abbreviation is used to determine the position of the ligand in the alphabetical order."

- **Explanation:** When dealing with abbreviated ligands, the alphabetical order is determined by the first letter of the abbreviation. For example, if we have ligands abbreviated as "bpy" (for bipyridine) and "en" (for ethylenediamine), we would consider "b" from "bpy" and "e" from "en" for ordering. Thus, this statement is **true**.

### Conclusion
- Statement I is false.
- Statement II is true.

### Final Answer
The correct option is that Statement I is false and Statement II is true.
