8 сент. 2015 г. · Bond angles mainly depend on the following three factors:- · sp3- 109°28′ · sp2- 120° · sp- 180° · Bond angle is affected by the presence of lone ... |
14 июн. 2018 г. · The answer is to use VESPR (Valence Shell Electron Pair Repulsion) Theory. The basic idea is that electron pairs, being negatively charged, repel each other. |
21 мар. 2018 г. · Bond angle depends on both hybridisation and number of lone pairs around d the central atom which depends on the number of groups surrounding central atom. |
27 дек. 2020 г. · Bond angles in a molecule can be measured experimentally using various techniques. Here are three commonly used methods. |
21 мар. 2017 г. · If the hybridisation is same then check the no of lone pair (the more the no of lone pair the less the bond angle).ex H2O and NH3 have the same ... |
7 нояб. 2019 г. · The lone pairs of electrons force the bond pairs of electrons closer to each other and this results in a smaller bond angle within the molecule. |
27 окт. 2012 г. · The oxygen lone pairs lie CLOSER to the oxygen atom, and so tend to compress the ∠H−O−H ∠ H − O − H bond-angle down from the ideal angle of ... |
28 нояб. 2018 г. · There are many methods for determining of bond angles and bond lengths in chemical compounds such as X-ray analysis, neutron diffraction, electron diffraction. |
16 дек. 2017 г. · A lone pair tries to repel bond pair resulting in the decrease of bond angle. For example:- Bond angle of CH4( no lone pair) is 109° but the ... |
6 окт. 2014 г. · The bond angles are affected by the geometry of the molecule as well as distortion effects from lone pair of electrons on the substituent atoms. |
