Zeisse's-salt Ferrocene and Dibenzene chromium are the example of _________bonded organometallic compounds.

Answer

To answer the question, "Zeisse's salt, ferrocene, and dibenzene chromium are examples of _________ bonded organometallic compounds," we can follow these steps:

### Step 1: Identify the Compounds
We need to recognize the compounds mentioned in the question:
- Zeisse's salt (Potassium platinum(II) chloride complex)
- Ferrocene (Iron complex with cyclopentadienyl ligands)
- Dibenzene chromium (Chromium complex with benzene ligands)

### Step 2: Understand the Bonding in Each Compound
Next, we analyze how these compounds are bonded:
- **Zeisse's Salt**: Contains platinum bonded to ethylene (C2H4) through a π (pi) bond, indicating a type of bonding that involves the overlap of p-orbitals.
- **Ferrocene**: Features iron (Fe) bonded to two cyclopentadienyl (C5H5) ligands through π (pi) bonds, which also involves the overlap of p-orbitals.
- **Dibenzene Chromium**: Contains chromium bonded to two benzene (C6H6) rings through π (pi) bonds, again indicating the overlap of p-orbitals.

### Step 3: Determine the Type of Bonding
From our analysis, we see that all three compounds involve π (pi) bonding due to the interaction of the metal with the p-orbitals of the ligands. This type of bonding is characteristic of organometallic compounds where the ligands are capable of forming π bonds with the metal.

### Step 4: Fill in the Blank
Based on our understanding, we can conclude that Zeisse's salt, ferrocene, and dibenzene chromium are examples of **"π-bonded"** organometallic compounds.

### Final Answer
Zeisse's salt, ferrocene, and dibenzene chromium are examples of **π-bonded** organometallic compounds.
