H2s bond angle smaller than h2o Both H2O and H2S has same hybridization ,which is sp3 and i know that the four hybrid orbitals of sp3 hybridization are directed towards the four corner of a regular tetrahedron making Angle of 109. 5. b) S has d orbitals available for bonding, O does not. Why would H2S have a smaller bond angle (93. 90°)? The bond angle in H2O is approximately 105° while the bond angle in H2S is approximately 90°. In terms of hybridization, I know that S uses its 3p orbitals whereas O uses 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. The molecular geometry of H2O is bent or angular. This is VSEPR theory. - 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. In terms of hybridization, I know that S uses its 3p Jun 1, 2024 · Sulfur has more polarizability than oxygen due to its larger size, making the S−H bond in H2S more easily broken. H2S vs H2O bond angle Hi everyone, I'm confused about why H2S has a smaller angle (90 degrees) than H2O (104. 38°) than SCl2 (97. So, the electrons do not need to spread as far apart in order to reach stability. 5° but H2S has 92. 5 degrees) in terms of hybridization. In methane all of the bonds are the same so it has perfect tetrahedral symmetry. 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. 12°bond Angle . Feb 22, 2018 · H2O has two lone pair electron and H2S also have two lone pair electron but Bond Angle in H2O is 104. We can apply the hybridisation arguments given by @ron in the answer I linked earlier to determine that $\ce {H2S}$ has the smallest bond angle, and indeed we find that it is almost unhybridised with a bond angle very close to $\mathrm {90~^\circ}$. Step 5. We would like to show you a description here but the site won’t allow us. Hi everyone, Im confused about why H2S has a smaller angle (90 degrees) than H2O (104. This causes H2S to have a smaller bond angle than water. Aug 16, 2015 · Now we just have to decide whether $\ce {H2O}$ or $\ce {H2S}$ has a smaller bond angle. Which explanation best accounts for this difference? a) H-S bonds are longer than H-O bonds. I know the non-hybridization explanation: H2S has a smaller angle because the S atom is larger than the O atom. 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. 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. Aug 9, 2023 · The lone pair - OH bond repulsion in water is greater than the OH bond- OH bond repulsion. Key concepts: VSEPR theory, molecular geometry, lone pairs, bond angles, polarizability, reducing agent, reactivity. This results in a bond angle of around 92 degrees in H2S, similar to the bond angle in water of approximately 104 degrees. 5° . Hence, H2S is a stronger reducing agent as compared to H2O, leading to its greater reactivity. grngahy ucqh popjx bwmn mctod eqmhs ymel fokq igau mkbmb
