I would also consider looking up videos on youtube or the ones that Dr. Lavelle has posted on the class website since I found those to be really helpful.

Ashvi_Luthra_4H

If LDFs are supposed to be commonplace and weak, how can they be stronger than dipole-dipole interactions?

Ashvi_Luthra_4H

When discussing coordinate compounds and their charge, why do we say that H20, amongst other molecules, have 0 charge?

Ashvi_Luthra_4H

Thank you so much!

Ashvi_Luthra_4H

Why is it that chlorine only attaches to guanine but none of the other base pairs, like A or T?

Ashvi_Luthra_4H

What exactly are the roles of ligands in biological processes and what do they connect to in the body?

Ashvi_Luthra_4H

Which molecules in the air have the biggest impact on the development of acid rain?

Ashvi_Luthra_4H

Does anyone have any tricks for remembering how to name the compounds other than examining the table?

Ashvi_Luthra_4H

Once the d orbital is introduced, what kind of bond does it make?

Ashvi_Luthra_4H

Should the conjugate base have a higher Ka than its acid? I saw an example on the board of a study session that implied this. If so, why?

Ashvi_Luthra_4H

What exactly gives molecules like H20 their amphoteric properties?

Ashvi_Luthra_4H

I think that there is a slight curve at the end of the class, but there is no curve on individual assignments

Ashvi_Luthra_4H

Why do we not consider double bonds or triple bonds when calculating regions of e- density and the shape of the molecule?

Ashvi_Luthra_4H

Would a change in boiling point, viscosity, etc. be more affected by having stronger bonds, such as a double vs. a single, or is it more related to shape?

Ashvi_Luthra_4H

Why is it that sigma bonds can be rotated while rotation will break a pi bond?

Ashvi_Luthra_4H

Why is it that sigma bonds can be rotated but pi bonds are fixed?

Ashvi_Luthra_4H

If resonance structures mean that the bond lengths will be considered the same, then then in what context do we discuss them in? Is it only relevant to molecules in which resonance structures are not present?

Ashvi_Luthra_4H

I know that salts have ionic bonds, while molecules have covalent bonds, but I do not exactly understand what properties having these bonds give? As in, what about having an ionic/covalent bond makes something a salt/molecule?

Ashvi_Luthra_4H

How does distortion effect the interaction potential energy and why does an increasing size or molar mass increase it?

Ashvi_Luthra_4H

Because of their un-neutral charges, are cations and anions more favorable for polar bonds, or does it not make a difference?

Ashvi_Luthra_4H

Are bond angles shifted during dipole interactions, as in another molecule can change the angle or shape just by being nearby?

Ashvi_Luthra_4H

Are there cases which a double bond and a single bond can be the same length? Is bond length dependent on what atoms are involved?

Ashvi_Luthra_4H

You can look at how many valence shells there are. The more shells, the less electronegative.

Ashvi_Luthra_4H

I believe it also has to do with which atom is the least electronegative, which in this case would be Nitrogen

Ashvi_Luthra_4H

They are a series of spectral emission lines of a hydrogen atom that went from a higher energy level to a lower one. It is calculated by using the empirical equation.

Ashvi_Luthra_4H

I think there is more shielding in the p- orbitals and up. Electrons in the s- orbital cause the shielding to the other orbitals. Since they are closer to the nucleus, they block some of the pull to the other electrons, so the electrons in the other orbitals are as a result at a higher energy level.

Ashvi_Luthra_4H

For the electron configuration cations and anions, will we be told what element it is supposed to be for a problem since cations and anions share electron configurations with other elements?

Ashvi_Luthra_4H

When we calculate the energy of a photon, do we include kinetic energy every time, and why or why not?

Ashvi_Luthra_4H

I believe that part of the reason there is such a big gap initially is that the electrons have a stronger pull to the nucleus because it is so close in n=1, so it requires more energy to remove the electron. As the n increases, there is less pull along with greater shielding, so it requires less ene...

Ashvi_Luthra_4H

In what kind of a situation would we want to eject electrons, and what are the exact results of this?

Ashvi_Luthra_4H

He said we will need to know once he teaches us to name them, but until then, we will be provided with it

Ashvi_Luthra_4H

Can someone explain L39 from the TB 6th edition?

Ashvi_Luthra_4H

When it asks to find the amount of moles of H2O in the Epson salts, why do we multiply 7*(5.15 g/246.48 g*mol-1)?
