What is the bond angle of water? - Chemistry Stack Exchange
2014年8月27日 · I have been trying to find out the bond angle of $\ce{H2O}$, but every site I visit has a different answer. So far, I have found the following angles listed: Site 1: 104.4º; Site 2: 107.5º OR 104.5º, depending on where you are in the article. Site 3: 104.5º
Why does bond angle decrease in the order H2O, H2S, H2Se?
2014年8月7日 · I will try to give u a most appropriate and short answer that u can understand easily See h20 has 104.5 degrees bond angle , h2s has 92degrees , h2se has 91degrees and h2te has 90degrees bond angles Draw diagrams of these u will find all of them have tetrahedral shape with 2 lone pairs , assume that no hybridization occurs and all these central ...
inorganic chemistry - Which has the largest bond angle between …
2016年8月19日 · The last part about "hydrogen atoms having easier time of crowding together closer to the 90 degree angle" is completely wrong: it isn't supported by experimental data. H2O has bond angle 104.45 degree and F2O has a bond angle of 103 degree. So clearly hydrogen is not happy to stay closer to 90 degrees. $\endgroup$ –
Estimation of the bond angle of water - Chemistry Stack Exchange
2015年11月24日 · We know from experimental data that $\ce{H-O-H}$ bond angle in water is approximately 104.5 degrees. If its two lone pairs were bonds (which is unfortunately impossible) also $\ce{O-H}$ bonds and a perfect tetrahedron resulted, then VSEPR theory would predict that the bond angle would be 109.5 degrees - this number can be easily derived using ...
Why Bond Angle is different? - Chemistry Stack Exchange
2018年2月22日 · H2O has two lone pair electron and H2S also have two lone pair electron but Bond Angle in H2O is 104.5° but H2S has 92.12°bond Angle . 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° .
Why does SO2 have a larger bond angle than H2O, H2S, and NH3
2015年8月16日 · Therefore we expect $\ce{SO2}$ to have the largest bond angle of the four molecules, and this is indeed the case. $\ce{H2O}$ and $\ce{NH3}$ are hydrides of the same period so we can use the first rule to determine that $\ce{H2O}$ has a smaller bond angle. Now we just have to decide whether $\ce{H2O}$ or $\ce{H2S}$ has a smaller bond angle.
Why does H2S have different bond angles to H2O but same MO …
2024年11月3日 · It says that there is no hybridization in for e.g hydrogen sulfide unlike water. I am not fully satisfied with this approach and I feel there must be a way to explain it using bond energies - MO theory (either canonical or localized). So I am wondering why H2S and H2O have such similar MO diagrams yet completely different bond angles
Bond angles for the hydrides - Chemistry Stack Exchange
2015年7月10日 · $\ce{H2O}$ has two lone pairs: the bond angle is contracted further due to the repulsion of two lone pairs to $104.5^\circ$. All of the Group IV hydrides will have perfect tetrahedral geometry due to having four bonds to the same atom and no lone pairs.
Why is the binding angle of HOF lesser than that of H2O, despite …
2019年8月9日 · F is very electronegative and thus the electron density of the O-F bond near O is less than that in O-H. If the electron density is farther away from the oxygen, then the 2 lone pairs of O squeeze the two bonding pairs closer together and the …
bond - A water molecule is bent. Why? - Chemistry Stack Exchange
2023年9月27日 · Consider the bent shape of $\ce{H2O}$ with a bond angle of $104°$. From my understanding, this is due to the lone pair repulsion between the 2 pairs of lone pair electrons. Hence, it adopts a tetrahedral structure, with a smaller bond angle due to the 2 lone pairs. We know this from VESPR. However consider the following diagram
