# why is the bond angle of H2S smaller than H2O?.

10.03.2007 · oxygen atom in water molecule has two lone pairs; due to small size of oxy, the lone pair-lone pair and the bond-pair bond-pair repulsion is large and as a result tend to push the molecule apart; however in H2S, the sulphur atom is greater in size and the lone pair tend to be far apart, thereby considerably reducing the repulsions and also the bond angle. that is the reason. The bond angles decrease in the following order: CH4 > NH3 >H2O >H2S all have four pairs of valence shell electrons. In the first three, these are arranged in a tetrahedral geometry. The additional repulsion of lone pairs over bonding pairs explai. H2O Bond Angles. Looking at the table, when we go from AX2, AX3 and all the way down to AX2N2, we will find out that the bond angle is going to be 109.5 degrees. So, using both the Valence Shell Electron Pair Repulsion VSEPR Theory and the table where we look at the AXN, we can quickly know about the molecular geometry for water. 28.08.2015 · Hydrogen sulphide has the same structure as water. The bonding in water is 104.5 degrees. As both have two bond pairs and two lone pairs of electron, shouldn't the bond angle in hydrogen sulphide be 104.5 degrees? Why is it 92 degrees? Is there anyway one can calculate the bond angles. Now we just have to decide whether $\ceH2O$ or $\ceH2S$ has a smaller bond angle. We can apply the hybridisation arguments given by @ron in the answer I linked earlier to determine that $\ceH2S$ has the smallest bond angle, and indeed we find that it is almost unhybridised with a bond angle very close to $\mathrm90~^\circ$.

10.01.2012 · The bond perspective relies upon on the ability orbitals at which the bonding between the two occurs additionally linked with the comparable is the spin states and whether it extremely is a 0.5 crammed or completely crammed orbital after bonding. the version of those features between Sulphur atonm and an Oxygen atom is the main to the size of bond perspective. 28.04.2013 · I know that the explanation for why H2O has a larger bond angle than H2S is because in O in H2O is more electronegative than S in H2S and hence attracts the bonding electrons closer to itself. This, and considering the fact that O is smaller than S, causes the bond pairs in H2O to be closer to each other and hence repel each other more, causing bond angle to increase. However, my question is.

The bond angles in the table below are ideal angles from the simple VSEPR theory, followed by the actual angle for the example given in the following column where this differs.For many cases, such as trigonal pyramidal and bent, the actual angle for the example differs from the ideal angle, and examples differ by different amounts. Water H 2 O is a simple triatomic bent molecule with C 2v molecular symmetry and bond angle of 104.5° between the central oxygen atom and the hydrogen atoms. Despite being one of the simplest triatomic molecules, its chemical bonding scheme is nonetheless complex as many of its bonding properties such as bond angle, ionization energy, and electronic state energy cannot be explained by. The lone pair of electrons takes up more space than a regular bonding pair since it it is not confined to be between two atoms, so it adds coulombic repulsion to the bonding pairs and compresses the angle. Therefore, the bond angle is less than the standard 109.5^@. It is actually \mathbf97.7^@.

In H2O, H2S, H2Se, H2Te, the bond angle decreases though all have the same bent shape. Why? H2S is bent, and bent at a smaller angle than is water. The bond angle in water is about 105 degrees which is predicated on the tetrahedral bond angle 109.5. But in H2S the bond angle is around 92 degrees. Both molecules are polar and exhibit dipole-dipole attractions, but in addition, water exhibits stronger hydrogen bonding. It is isoelectronic with CO 2, having two N=O double bonds and no unpaired electrons, so repulsion between the two regions of electron density is minimised by the 180° bond angle, and it is linear, as with CO 2. NO 2-has one more electron than NO 2, so it has a.

## Bond Angle of H2S Question? Yahoo Answers.

As we go down a period, the electronegativity decreases. Hence, sulphur is less electronegative than oxygen. The O-H bonds are drawn closer to each other. But they experience greater repulsion than than h2s n they move away. Hence, bond angle in H2O is104.5°. But in h2s bond angle is lesser due to lesser electronegativity and lesser repulsion. Answer: The correct order of bond angles will be < < <. Explanation: In case of, there are 2 lone pair of electrons on sulfur atom. These lone pairs will cause repulsion and hence the bond angle will decrease because the lone pair-lone pair repulsion's are more as compared to bond pair-bond pair or lone pair-bond pair. Therefore, the molecule will have a bent shape geometry similar to. The correct order of bond angles in H2S,NH3,BF3 and SiH4 is: asked Nov 21, 2018 in Chemistry by ranik 67.1k points neet 1 vote. 1 answer. Which one of the following compounds has the smallest bond angle in its molecule? asked Mar 29, 2018 in Chemistry by paayal 146k points atomic structure.

17.07.2007 · NH3, Pyramidal, bond angle 104.5 degree. TeCl2,angular, bond angle, 100 degrees. CCl4, Tetrahedral, 109degrees 28 minutes. SO2, angular, 120 degrees. H2O H2S 중심원자 결합각 bond angle ----- H2O의 각도 = 104.5° H2S의 각도 = 92.1° 산소는 2주기 원소이고, 황은 3주기 원소이기 때문에, 원자의 크기는 황이 더 크다. The expected bond angle would be ~109 o, but, just as with the water molecule, the lone pair - lone pair repulsion is greater than the bond pair - bond pair repulsion giving a bond angle of 104.7 o, almost identical with water 104.5 o, and note that oxygen and nitrogen have similar atomic radii. No, you can't have a bond angle between 2 points in the same way as you cannot have any angle using only two points. HCl is linear only in the sense that the only possible way to directly connect two points is via a straight line - there are no angles involved. By your argument a noble gas atom would have a bond angle. Give the approximate bond angle for a molecule with a tetrahedral shape. 180.

The trend in bond angles in H2O, H2S, H2Se, H2Te of 104.5, 92.3, 91 and 90 respectively. This can be explained by the application of VSEPR with some hand waving steric and inductive electronic arguments thrown in. 03.12.2007 · Hi, I was going through some of the exam papers when I saw that H2S hydrogen Sulphide has a linear shape. I wondered that when 2 of the 6 electron on sulphur bind to 2 hydogen ones to make a bond, it leaves 4 electrons on sulphur which makes it. Answer to: What is the bond angle of OF2?

Can you explain this answer? is done on EduRev Study Group by Class 12 Students.

The short version: Sulfur is more electronegative than hydrogen, so the "H-S" bond is polar with electron density higher on the sulfur atom. > This leads to "H"_2"S" being a polar molecule. However, the difference in polarity between "H" and "S" is very small, so neither the bond nor the molecule are very polar. The longer version: The difference in electronegativities of hydrogen 2.20 and. H2s are two H atoms attached as in H-H. If that is what you mean, it has no bond angle actually, it has one but it is 180 degrees as in a linear angle..
