Options

A. Maximum there halogen atoms can lie in same plane
B. Both axial and equatorial plane may have equal number of atoms
C. `As-Cl` bond length is longer than `As-F` bond length .
D. Maximum five atoms can lie in equatorial plane.

Explanation

To analyze the statements regarding the molecule As(CH₃)F₂Cl₂, we will break down the information provided in the video transcript step by step.

### Step 1: Understanding the Molecular Structure
The molecule As(CH₃)F₂Cl₂ consists of an arsenic (As) atom bonded to three groups: one methyl group (CH₃), two fluorine atoms (F), and two chlorine atoms (Cl). The molecular geometry can be determined by considering the arrangement of these atoms around the arsenic atom.

**Hint:** Visualize the molecular structure using VSEPR theory to determine the arrangement of atoms.

### Step 2: Determining the Planes of Atoms
In the structure of As(CH₃)F₂Cl₂, the two fluorine atoms are positioned in the axial positions, while the two chlorine atoms are placed in the equatorial positions. This arrangement allows us to analyze the planes in which the atoms lie.

**Hint:** Draw a 3D representation of the molecule to identify which atoms lie in the same plane.

### Step 3: Evaluating the Statements
1. **Maximum three halogen atoms lie in the same plane:**
- When visualizing the molecule, we can see that the two fluorine atoms and one chlorine atom can lie in the same plane, confirming this statement as correct.

2. **Both axial and equatorial planes may have equal number of atoms:**
- By analyzing the axial and equatorial positions, we find that both planes contain the same number of atoms (5), making this statement correct.

3. **AsCl bond length is longer than AsF bond length:**
- The bond length comparison is based on atomic size. Chlorine is larger than fluorine, thus the As-Cl bond length is indeed longer than the As-F bond length, confirming this statement as correct.

4. **Maximum five atoms can lie in the equatorial plane:**
- In the structure, we can observe that there are five atoms (two Cl, one As, one C, and one H) that can lie in the equatorial plane, confirming this statement as correct.

**Hint:** Check each statement against the molecular structure and bond lengths to verify their correctness.

### Conclusion
After analyzing the structure and evaluating the statements, we conclude that all four statements regarding the molecule As(CH₃)F₂Cl₂ are correct.
