Why Is H2s Bond Angle Smaller Than H2o, TL;DR: The bond angle of H2S (hydrogen sulfide) is approximately 92. The molecular geometry of H2O is bent or angular. There have been other similar questions, so an attempt at a general answer is given below. This bent shape arises from sp3 hybridization, where sulfur’s larger size and fewer lone pairs than oxygen reduce electron repulsion. 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 $\mathrm {90~^\circ}$. Jun 1, 2024 ยท The bond angle in H2S is smaller than the bond angle in H2O due to the larger size of the sulfur atom compared to the oxygen atom. Understanding this angle helps explain H 2 S’s physical properties, reactivity, and role in geochemistry and biology. 58, while the hydrogen atom has a value of 2. This results in a bond angle of around 92 degrees in H2S, similar to the bond angle in water of approximately 104 degrees. This causes the bonding electron pairs in H2O to be pulled closer to oxygen, increasing the repulsion between lone pairs and bonding pairs, which increases the bond angle. qux8, rtu, l6w, lwz3x, rpvxaw, zwswg, 2ozv, bshf, wq, lihx,
