Test 2 Review

[Jose Robles 1D]

From what lesson onward do we study for test 2? It's not cumulative, so what did we stop at before the midterm?

[kpang_4H]

I think vsepr and molecular shape is where we start for test 2, and intermolecular forces

[kim 2I]

I'm pretty sure that the topics on test 2 will cover:
-VSEPR
-dipole moments and shape (non-polar/polar)
-identifying intermolecular interations
-lone pairs and the reason for their locations
-sigma and pi bonds

Dr. Lavelle also said that whatever we cover in the Monday lecture will also be on the test so keep a heads up on that!

Everything that was not included in the midterm.

Everything after the midterm

[kendal mccarthy]

My TA said

IMF, H bonding, molecular shape, VSPER, polarity from VSPER structure, bond angles, polar/non polar, intro sigma and pi bonds

[Sunia Akaveka 4I]

3F.4-3F.5, also the topics on Lavelle's Outline 4: Molecular Shape and Structure, that doesn't include hybridization (up to sigma/pi bonds).

What do we need to know for "lone pairs and the reason for their locations"? I'm not sure what this is referring to

I think its talking about molecules with the formula AX4E because the electron geometry is trigonal bipyramidal and the lone pair can be on either the axial or the equatorial plane. The lone pair is on the equatorial plane because it maximizes the distance between the lone pair and the other atoms.
