Why is h2s bond angle smaller than h2o. 90°)? The bond angle in ...
Why is h2s bond angle smaller than h2o. 90°)? The bond angle in H2O is approximately 105° while the bond angle in H2S is approximately 90°. 38°) than SCl2 (97. Apr 11, 2018 · (c) Bond angle of H 2 S (92°) < H 2 O (104°31). Explain why H2S has a lower boiling point than both H2O and H2Se. Is that an acceptable answer? Explain why H2S has a lower boiling point than both H2O and H2Se. As the electronegativity of the central atom decreases, bond angle decreases. Why would H2S have a smaller bond angle (93. This causes H2S to have a smaller bond angle than water. Step 5. Sep 3, 2025 · Why is H2S bond angle smaller than H2O if both have sp3 hybridization? Though both are sp3 hybridized, sulfur’s lone pairs repel differently due to its larger size and electronegativity. This results in a bond angle of around 92 degrees in H2S, similar to the bond angle in water of approximately 104 degrees. Also, the H-S bonds are less polar than the H-O bonds so therefore there's less repulsion. Jun 19, 2025 · Why is the bond angle in H2S smaller than that in H2O, although both possess a bent shape? The bond angle in a molecule depends on the arrangement of bonding electrons around the central atom and the repulsion between these electron pairs. 5°. In the present case, S is less electronegative than oxygen. As the electronegativity of the central atom decreases the lone pair of electrons lie further from it and therefore lp- lp repulsion decrease. Solution: Bond angle of H 2S (92∘) <H 2O(104∘31). Key concepts: VSEPR theory, molecular geometry, lone pairs, bond angles, polarizability, reducing agent, reactivity. We would like to show you a description here but the site won’t allow us. The singlet and triplet state molecules show that the singlet has two electrons in the orbital and has a smaller angle than the triplet state with just one electron here and one in the non-bonding , thus the triplet ground state bond angle is expected to be larger than the singlet. Hence, H2S is a stronger reducing agent as compared to H2O, leading to its greater reactivity. "Do not use electronegativity in your answer. - Therefore, the H-S-H bond angle is smaller than the H-O-H bond angle because sulfur's larger size results in a more open structure. Oct 6, 2019 · Explanation: In the water molecule oxygen atom is present which is more electronegative than sulfur in H2S ( electronegativity decreases down the group) . Bond angle of H2O is smaller than that of H2S 4. However, assuming hybridization occurs why would H2S have a smaller bond angle? In H2S the sp3 hybrid orbitals are bigger than H2O and so the bond pair-bond pair repulsion decreases so with just this statement, the bond pairs should be able to come closer to each other.

Jun 1, 2024 · Sulfur has more polarizability than oxygen due to its larger size, making the S−H bond in H2S more easily broken. Which explanation best accounts for this difference? a) H-S bonds are longer than H-O bonds. 5. A larger central atom (sulfur) leads to a decrease in bond angles because the bond pairs are further apart due to the larger atomic radius. Both have the same bond angle. . Thus bond pairs in H 2 S are more away from the central atom than in H 2 O and thus repulsive forces between bond pairs are smaller producing smaller bond angle. The H2S bond angle is about 93°, H2O is 104. " My thoughts are: Since the central atom, S, is larger, the less the H's have to spread out. 2. None of the above. Bond angle of H2O is larger than that of H2S 3. Thus, bond pairs in H 2S are more away from the central atom than in H 2O and thus repulsive forces between bond pairs are smaller, producing smaller bond The correct statement regarding the bond angle of H2O and H2S is: 1. Hence bond angle decrease. The molecular geometry of H2O is bent or angular. wmposolkjwarzkbhlyaxysbujspeqdyitjpotxcqdbdcrbnfb
