33 views Which species has the smaller bond angle, H3O + or H2O? Determine the electron geometry (eg), molecular geometry (mg), and polarity of SO3. 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. Re: Bond angles of H3O+ Post by Reva Kakaria 1J » Mon Nov 19, 2018 9:27 pm . Want to see the step-by-step answer? 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. In , there is no lone pair of electrons, only bond pair bond pair repulsion exists which is very negligible.So the bond angle remain lone pair-bond pair repulsion >bond pair-bond pair repulsion. The bond angle of H3O+ predicted using VSEPR (valence shell electron pair) theory would be 107o. Which species has the smaller bond angle, H3O + or H2O? B) H2O. Since H3O+ has a lone pair and three bonds… The H−O−H bond angle is approximately 113°, and the center of mass is very close to the oxygen atom. Thus, the bond angle is slowly expanded until an optimum is reached at 104.5°. For H3O^+ provide a Lewis structure, predicted VSEPR molecular geometry, bond angle, and indicate whether the compound is polar, non polar, or polyatomic ion. A better consideration is to start from a hypothetic bond angle of 90° (two p orbitals used for a sigma bond each) but then realising that the hydrogens would end up too close together. Explain?

The bond angles in are greater than and less than .. Reason:- Valence shell electron pair repulsion (VSEPR) theory states that- lone –lone repulsion. Want to see this answer and more? Thank you. Because the base of the pyramid is made up of three identical hydrogen atoms, the H 3 O + molecule's symmetric top configuration is such that it belongs to the C 3v point group. Asked Aug 9, 2020. The explanation that your source gives for the bond angle of water being smaller than 109° is actually wrong. check_circle Expert Answer. I am assuming you are asking for a predicted bond angle rather than the actual bond angle. Check out a sample Q&A here. Take one off for the +1 ion, leaving 8. Oxygen is in group 6 - so has 6 outer electrons. … Explain? Can someone please help me determine the bond angles at the central atom of the hydronium ion, H3O+? A) H3O+ B) H2O. Top. Step-by-step answers are written by subject experts who are available 24/7. Which species has the smaller bond angle, H3O+ or H2O? Add 1 for each hydrogen, giving 9.
