Will we need to know pentagonal pyramidal, seesaw, square pyramidal, or t-shape? They're in the textbook but he didn't go over them in class.

I think unless he goes over them on by the end of the chapter, or if it shows up in the homework he assigned, we don't need to know them.

I don't think so but I think it is best to know the VESPR shape for conventional molecules just in case, like H2O.

Those models are added in once we learn how lone pairs affect the arrangement of atoms within a molecule.
For example, in H2O, there are two lone pairs on the oxygen and two bonding pairs. The two long pairs will repulse the bonded H and cause the shape of a water molecule to be bent.
Hence, the classification of its shape would be "bent," although the arrangement of the molecule itself is linear.
I am pretty sure he will discuss this next lecture.

all depends in Lavelle goes over it in class or if we have homework on them

I think we will be expected to know those additional VSEPR shapes because most are exceptions that arise when lone pairs are introduced onto central atoms, which is an idea Lavelle will likely go over in further depth next lecture.

I think we will need to know them, and Professor Lavelle will probably go over them in class on Friday. The other shapes result when lone pairs (rather than bonding pairs) occupy regions of electron density.

I believe we will learn these terms on Friday in Lecture and eventually they will be what we name our VSEPR models as, because they are more specific and telling of the actual shape of the molecule.

I'm pretty sure we will have to know those shapes just because we were assigned HW problems where some of the answers involved those shapes. Like other people mentioned, Professor Lavelle will probably go over them on Friday.

I would just worry about what we learned for right now, but he said he will be going over more in Fridays lecture so he might go over those then, and then they will probably be on the test.

I believe we only need to know the ones he goes over in the lectures.
