Consider the following two molecules and according to the given information select correct statement(s) about `AX_(2) and AY_(2)` :
where A: 16th group of 3rd period element
X: more electronegative than (A) and same group number of (A) ltbgt Y: Less atomic size than (A) and same period number of (A)

Options

A. The hybridization of central atoms are different in both compounds
B. The shape of both molecules are same
C. Both compounds are planar
D. The X-A-X bond angle is less than Y-A-Y bond angle

Explanation

To solve the problem regarding the molecules AX₂ and AY₂, we will follow these steps:

### Step 1: Identify the elements A, X, and Y
- A is a 16th group element from the 3rd period. The only element that fits this description is **Sulfur (S)**.
- X is more electronegative than A and in the same group as A. The element that fits this description is **Oxygen (O)**, which is above sulfur in group 16.
- Y is less in atomic size than A and in the same period as A. The element that fits this description is **Chlorine (Cl)**, which is in the same period (3rd period) but to the right of sulfur.

### Step 2: Write the chemical formulas for AX₂ and AY₂
- The compound AX₂ is **SO₂** (sulfur dioxide).
- The compound AY₂ is **SCl₂** (sulfur dichloride).

### Step 3: Determine the hybridization of the central atom in both compounds
- For SO₂, sulfur has a hybridization of **sp²** because it forms two double bonds (with oxygen) and has one lone pair.
- For SCl₂, sulfur has a hybridization of **sp³** because it forms two single bonds (with chlorine) and has two lone pairs.

### Step 4: Analyze the shape of both molecules
- The shape of SO₂ is **bent** due to the presence of one lone pair and the two bonded pairs.
- The shape of SCl₂ is also **bent** due to the presence of two lone pairs and two bonded pairs.

### Step 5: Compare the bond angles in both compounds
- In SO₂, the bond angle (O-S-O) is approximately **120°** due to the sp² hybridization.
- In SCl₂, the bond angle (Cl-S-Cl) is less than **109.5°** due to the sp³ hybridization and the presence of lone pairs.

### Step 6: Evaluate the correctness of the statements
1. **The hybridization of the central atom is different in both compounds.**
- **Correct** (SO₂ is sp², SCl₂ is sp³).

2. **The shape of both molecules is the same.**
- **Correct** (Both are bent).

3. **The bond angle XAX is less than XAY.**
- **Incorrect** (The bond angle in SO₂ is greater than in SCl₂).

### Conclusion
The correct statements about AX₂ and AY₂ are:
- The hybridization of the central atom is different in both compounds.
- The shape of both molecules is the same.
