Statement-1:In natural tris chelating complex, `[Co(acac)_3]`, in each ring the two `M-O` bonds are equal in length, as are two C-O and the two C-C bonds because.
Statement-2:In each ring resonance take place.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Explanation

To solve the question, we will analyze both statements and provide a step-by-step explanation.

### Step 1: Understanding the Complex
We are given the complex `[Co(acac)3]`, where `acac` stands for acetylacetone. This complex has a tris-chelating structure, meaning that three acetylacetone ligands are coordinated to the cobalt ion.

### Step 2: Drawing the Structure
To visualize the complex, we can draw the structure of one of the acetylacetone ligands. Each ligand forms a five-membered chelate ring with the cobalt ion. The structure can be represented as follows:

- Each acetylacetone ligand has two oxygen atoms (O) that coordinate to the cobalt (Co) and form a ring structure with carbon (C) atoms.

### Step 3: Analyzing Bond Lengths
In the rings formed by the acetylacetone ligands:
- The two `M-O` (metal-oxygen) bonds are equivalent in length due to the symmetrical nature of the chelate ring.
- Similarly, the two `C-O` (carbon-oxygen) bonds and the two `C-C` (carbon-carbon) bonds are also equal in length.

### Step 4: Understanding Resonance
The reason for the equality of bond lengths in the rings is due to resonance. In each ring:
- The double bonds can shift, allowing for the delocalization of electrons across the ring structure.
- This delocalization leads to an equal distribution of electron density, resulting in equal bond lengths.

### Step 5: Evaluating the Statements
- **Statement 1**: This statement is true because the bond lengths in the rings are indeed equal.
- **Statement 2**: This statement is also true as resonance occurs in the rings, which explains why the bond lengths are equal.

### Step 6: Conclusion
Since both statements are true and Statement 2 correctly explains Statement 1, we conclude that the answer is that both statements are true, and Statement 2 is the correct explanation for Statement 1.

### Final Answer
Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation for Statement 1.
