2021年11月16日 · Because each element pair has different amounts of repulsion from each other the exact angle in bonds with lone pairs depends on the composition. (For example NH3 has bond angles of 107 degrees, but NF3 (also trigonal pyramidal) has bond angles of 102.5 degrees, but both values are slightly less than 109.5 degrees).

2024年11月15日 · There are some angles in situations that are good to memorize (such as the bond angles being 120 in a trigonal planar) but as far as I know I don't think it's expected for us to be able to calculate an exact value for an angle in something like ClO2. Of course if Dr. Lavelle says something otherwise in class or on here, go with what he says.

2024年11月15日 · Hi, my TA mentioned that double and triple bonds are treated the same as single bonds, because they are all counted as just 1 region of electron density each. Therefore, I believe double and triple bonds don't affect bond angle any more than a single bond.

2019年11月20日 · Yes, it would have a bond angle of 180 degrees. And for AXE2, it should also be 180 degrees. The molecular geometry indicates the actual observed shape since it accounts for repulsion from lone pairs, while the electron geometry just …

2023年11月23日 · When a molecule has multiple central atoms, you analyze each central atom separately following the VSEPR steps to determine the molecular geometry and bond angles around each.

2024年11月15日 · The reason that the bond angles do not add up to 360 degrees is because the bond angles are represented in a 3D shape, not in a plane like how we are used to seeing it.

2024年11月18日 · Hi! The bond angle increases with the s-character because of the way in which electrons are organized so that they experience minimum repulsion. The greater the s-character, the closer the electrons are to the nucleus which increases the strength of the bond as well has the bond angle. Sp orbital is composed with one s orbital and one p orbital.

2023年11月26日 · If the sgteric number is 2 there is a 180 degree angle for a linear shape. If its 3 without lone pairs its trigonal planar with 120 degrees, however if there are lone pairs it's a bent shape with an angle of less than 120 degrees. The steric number can therefore help affect bond angles but it is not the only thing to take into account.

2021年11月9日 · Molecular geometry focuses on the bonded atoms only, so because the 2 bonded atoms lay in one line, this creates a linear shape, in which the bond angle is 180 degrees. Top Jericho Ansay 1C
