So its H2O bond angle 104.5 o is slightly smaller than pure tetrahedral 109 o. de Broglie wave interference explains H2O angle [ Only Coulomb repulsion, six oxygen electrons form "right angle" ] (Fig.23) Six oxygen valence electrons closer to tetrahedron. Justify Answer. (b) Two S O bonds in SO2 are identical. Explain why : (a) H2S is more acidic than H2O. 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. 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. 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. Steric Number Video Chemical Bonds Khan Academy. C. Presence of hydrogen bond. The methylene radical CH2 has just 6 electrons around the central carbon. The bond angles in the table below are ideal angles from the simple VSEPR theory (pronounced "Vesper Theory"), followed by the actual angle for the example given in the following column where this differs. The bond angle between H—C—H is 109.5° which is called the tetrahedral angle. What is the H-C-H bond angle? Correction: H2O has 104.5 degrees and the tetrahedral ball-stick model is therefore a little inaccurate. 0 0. you got this from mastering chemistry.com.
