Given below are two statements :

Statement I : $$\mathrm{SO}_{2}$$ and $$\mathrm{H}_{2} \mathrm{O}$$ both possess V-shaped structure.

Statement II : The bond angle of $$\mathrm{SO}_{2}$$ is less than that of $$\mathrm{H}_{2} \mathrm{O}$$.

In the light of the above statements, choose the most appropriate answer from the options given below:

Both Statement I and Statement II are incorrect
Both Statement I and Statement II are correct

Explanation

JEE Main 2023 (Online) 13th April Evening Shift Chemistry - Chemical Bonding & Molecular Structure Question 75 English Explanation
Statement I: Both SO₂ and H₂O have a V-shaped (or bent) molecular structure. SO₂ has a central sulfur atom with two oxygen atoms and one lone pair, while H₂O has a central oxygen atom with two hydrogen atoms and two lone pairs. In both cases, the repulsion between the lone pairs and the bonded electron pairs leads to a V-shaped structure.

Statement II: The bond angle in H₂O is approximately 104.5° due to the tetrahedral arrangement of electron pairs (including the lone pairs) around the central oxygen atom. In SO₂, the bond angle is approximately 119°. The presence of a lone pair and the double bonds in SO₂ results in a different electron distribution, leading to a larger bond angle compared to H₂O.
