- For some reason we only list some of the angles. See the Kaplan table below.
Octahedral geometry has 90° bond angles occur between adjacent bonds and 180° bond angles occur between axial atoms.
Trigonal bypramidal has 3 associated angles: 120° Between Equatorial Bonds, 90° Between Axial and Equatorial Bonds, and 180° Between Axial Bonds. So the trigonal bypramidal card will have to be changed as well.
- We list several possible molecular shapes with varying numbers of bonded vs non bonded electrons. Previously we just listed the angles as bond angles but this is misleading and should referred to as ideal bond angles as they assume that there are no lone pairs of electrons. If lone pairs are present actual bond angles vary.
i think the assumption is that 90 is the same as 180, if i have 90 degree angle between 3 thing then would be same thing as having 90 and 180,
I understand why 180 might be intuitive if you know what these structures look like but I’m not sure I agree with that it makes sense to only list some of the angles.
ok so if we change the question for this one shouldnt we also do the same for the others to ensure consistency
im fine with 180
