Find your group chat here >> start new discussion reply. as electronegativity of O is more than S so bond angle of H2O more than H2S. bond periodic-trends hybridization molecular-structure. The bond angles decrease in the following order: CH4 > NH3 >H2O >H2S all have four pairs of valence shell electrons. Both NH3 and H2O have a tetrahedral electronic geometry, but in both molecules the bond angle is less than the predicted 109° or so. Firstly, ‘S’ in SO2 is sp2 hybridised ,and central atoms of H2O,H2S and NH3 are sp3 hybridised.So, the bond angle in case of SO2 is nearly 120 degree, whereas the bond angles in case of H2o,H2S and NH3 are nearly equal to 109.5 degree. letticia g. 1 decade ago. bond angle in H2O Bond angles in NH3. Is there a qualitative reason for this? In H2O, H2S, H2Se, H2Te, the bond angle decreases though all have the same bent shape.

Update: ok Thanks] i was correct :] Answer Save. But in the case of NH3 and H2O molecules, their central atoms N and O have a lone pair of electrons. Thus, bond angle of Cl2O is greater than bond angle of H2O. This fact can be explained with the help of: A. Valence shell electron pair repulsion theory (VSEPR) B. Molecular orbital theory. Walsh Diagram Wikipedia. The bond angle around B in B C I 3 and B F 3 is same . Join. Due to more electronegativity of oxygen electron cloud shift towards it and this lead to increase in b.p-b.p repulsion. Csonn T3 Chemical Bonding. 0 0. Why?

Have you registered for the PRE-JEE MAIN PRE-AIPMT 2016? 1.Lone pair 2.Bond pairso: What is lone pair and bond pair of electrons?In simple words ,lone pair is the unshared pair of electron and the bond pair… (B) lone pair-bond pair repulsion. This lone pair causes repulsion of electrons and hence causes the decrease in the normal tetrahedral angle which gets reduced to 107° in NH3 and 104.5° in H2O. The repulsion is greater; the electrons want to get away from each other more because they have like charges (creating larger bond angles) 0 0. nedeau. The unshared pairs of electrons are not as constrained as are electrons in covalent bonds and so they occupy more than their "fair share" of space, forcing the bond angles to be less than perfect. 0 0. you got this from mastering chemistry.com. 7,955 8 8 gold badges 43 43 silver badges 93 93 bronze badges. Relevance. According to VSEPR theory the rupulsive force between bond pairs and lone pairs are not same. The carbons are sp2, so the angles are 120 o. (C) bond pair-bo It's hard to believe CO2 is exactly 180 degrees unless there were some symmetry, but the same symmetry argument should apply to H2O then. 1 answer.

H2O AM product range Discover the H2O product range(*), which consists of absolute and relative performance strategies. C. Presence of hydrogen bond. In H2O, oxygen is more electronegative, electrons of two O-H bonds are more attracted towards oxygen atom. The bond angle of Cl2O is larger than H2O because in case of Cl, P double bonds can be formed as they can expand their shells , double bonds cause more repulsions , and hence bond angle increases. The bond angle in H 2 O is 1 0 4. 302 views. (c) SF6 is inert and stable but SF4 is reactive. As we know in both structure two bond pair and two lone pair are present and both has tetrahedral geometry. Gaurang Tandon. Lv 4.
