Q3 is the question I require help.
I am confused for Atom A, because I think it’s a trigonal pyramidal with a bond angle of 107 degrees. But the book says that the bond angle is 120 degrees,
So I am in confusion.

I believe that the book is wrong in the nomecature because if it where a trigonal pyramidal it would have to have a lone pair of electrons (for example, ammonia) for it to repel so it has the "pyramid" shape, since all the electrons are bonded it is trigonal planar, sorry.

So that’s why I am confused

I thought that as well, because it should have a lone pair and three bonded pairs.
So that’s why I am confused

3 areas of electron density (2 single, 1 x double) repulsion is equal from the three regions, so 120 degrees and trigonal planar

Thank you guys for your help.
I really appreciate it for clearing out my confusion.
