VendorConnect - Port of Seattle. Answer. 302 views. Correction: H2O has 104.5 degrees and the tetrahedral ball-stick model is therefore a little inaccurate. In the first three, these are arranged in a tetrahedral geometry. as electronegativity of O is more than S so bond angle of H2O more than H2S. Based on the bond angles in CH4 , NH3 , and H2O, rank the magnitude of these repulsions. The bond angle between H—C—H is 109.5° which is called the tetrahedral angle. p-block element; jee; jee mains; Share It On Facebook Twitter Email. 4 years ago.

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. Can you explain this answer? Valence Shell Electron Pair Repulsion Theory Vsepr. Lv 7. Gaurang Tandon. The fund will offer a total … Please help! POST Answer. I know that bond angle decreases in the order $\ce{H2O}$, $\ce{H2S}$ and $\ce{H2Se}$. 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. 8 years ago. 49 16. fossa. … ← Prev Question Next Question → 0 votes .

H-O-H bond angle in H2O is 104.5° and not 109° 28' because of (A) lone pair-lone pair repulsion. (c) SF6 is inert and stable but SF4 is reactive. 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. rank from strongest to weakest repulsion: BP-BP LP-LP BP-LP.
