III) `N_(2) O_(5)`  molecule is angular
The correct combination is

Options

A. All are correct
B. I & III are correct
C. II & III are correct
D. I & II are correct

Answer

To solve the question regarding the statements about the oxides of VA group elements, we will analyze each statement one by one based on the molecular structures of the compounds mentioned.

### Step 1: Analyze the first statement about N₂O
- **Compound**: N₂O (Dinitrogen monoxide)
- **Structure**: The structure of N₂O can be represented as N≡N-O or N=N=O. In both representations, the nitrogen atoms are bonded to each other and to an oxygen atom.
- **Hybridization**: The nitrogen atoms in N₂O exhibit sp hybridization, which leads to a linear shape.
- **Conclusion**: The first statement "N₂O molecule is linear" is **correct**.

### Step 2: Analyze the second statement about NO₂
- **Compound**: NO₂ (Nitrogen dioxide)
- **Structure**: The structure of NO₂ can be represented as O=N-O. The nitrogen atom is bonded to two oxygen atoms, and there is a lone pair on nitrogen.
- **Hybridization**: The nitrogen in NO₂ exhibits sp² hybridization due to the presence of one lone pair and two bonding pairs, leading to a bent or angular shape.
- **Conclusion**: The second statement "NO₂ molecule is angular" is **correct**.

### Step 3: Analyze the third statement about N₂O₅
- **Compound**: N₂O₅ (Dinitrogen pentoxide)
- **Structure**: The structure of N₂O₅ can be represented as O=N-O-N=O (with additional oxygen atoms). The nitrogen atoms are bonded to oxygen in a way that forms a planar structure.
- **Hybridization**: The nitrogen atoms in N₂O₅ exhibit sp³ hybridization, and the molecule is planar due to the arrangement of the bonds.
- **Conclusion**: The third statement "N₂O₅ molecule is angular" is **incorrect**; it is actually planar.

### Final Conclusion
- The correct combination of statements is:
- I) Correct
- II) Correct
- III) Incorrect

Thus, the correct answer is the combination of statements I and II being correct.
