I got this wrong on the test but that’s okay.

marg44

Thanks chem community for all the help this quarter. See you in 14b:)

marg44

Can someone explain 41c? I'm confused as to why the nitrogen with the lone pair can accept the proton but not the oxygen.

marg44

Will we have to write the molecules in reverse on the test so we know which lone pair is binding or did Lavelle just do that for the examples so it was more clear for us?

marg44

Does anyone know what he will ask about the chemo drugs? will it be more conceptual and like how the molecule is effective?

marg44

For these sigma and pi bonds, is one bond stronger than the other? Or are they of equal strength?

marg44

I think Lavelle said it would be more conceptual but I’m not sure if that means entirely conceptual or just similar to the homework problems.

To answer your question the steric number is the number of atoms bonded to a central plus the number of lone pairs on that atom. It’s used to help determine molecular shape using VSEPR

Are we going to be dealing with resonance structure and delocalized atoms on this Friday’s test?

marg44

I think it is important to know the general trend of electronegativity on the periodic table.

marg44

Certain Dipole moments will cancel each out when they are moving in opposite direction like when the attraction moves away from the center such as in CH4.

marg44

I'm not sure if it's the only way but it is the only way Lavelle has taught us in class.

marg44

It happens when an ion or dipole makes another atom or molecule a dipole that wasn’t a dipole before. They’re pretty weak forces.

marg44

Are we going to need to know how to name the bond angles???

marg44

For this question it asks to list all possible intermolecular bonds and since hydrogen bonds are dipole forces should I list both? Or just hydrogen bonds?

marg44

Why will the energy emitted be positive if it's emitted won't it be negative because it's losing energy????????????

marg44

Can someone help me with #1? I tried a couple things but I keep getting wild numbers.

marg44

Ionziation energies increase going up and to the right so would Helium have the highest ionization energy?
