Re: Bond Angles [ENDORSED]

Hybridized orbitals have no effect on the shape. Rather, only the number of bonded atoms vs. number of lone pairs really determines the shape of the compound.

Re: Hybridization/Hybrid Orbitals of Pi Bonds

Yes it does. The hybridized p orbitals are used for the formation of sigma bonds, while the leftover unhybridized p orbital(s) are used for pi bonds.

Re: Dentates

Yes, usually, spotting these out till help determine what -dentate a ligand is. I don't believe Dr. Lavelle will ask anything in deeper context than that.

Re: Determining whether ligand is mono-, bi-, or polydentate

Usually, you will check to see how many Nitrogens there are in the compound since these atoms will most likely have a lone pair that can attach to the central atom. However, there way be other atoms, like oxygen, that can also have a lone pair and can attach as well. Most likely, in the compound, th...

Re: What is delocalized bonding? [ENDORSED]

You will usually experience delocalized bonding when encountering a compound that has resonance. Most likely, this compound will have pi bonds that are able to be shared across the entire compound. In this case, the use of the unhybridized p orbitals will allow the pi bonds to be equally shared amon...

Re: Kc

Usually, you will use Kp when dealing with gasses since it technically defines partial pressure. Kc is more used when determining the equilibrium concentration, or molarity. However, since both use the exact same process, it's fine to go either way.

Re: Concept of deBroglie

De Broglie only applies to "objects with mass." Therefore, when determining the wavelength of an electron at a certain velocity, you would use De Broglie. However, since light has no mass, this equation can't apply.

I don't think Dr. Lavelle will ask us to name specific acids/bases we haven't seen. But in the future, it just takes memorization of these compounds.

Pi bonds and Sigma bonds

What hybrid orbitals bond together in a linear molecule of ethyne? (H-C---C-H). The three dashes between carbons represent a triple bond. How exactly do each hybrid orbital bond to form sigma and pi bonds?

Hybridization in Double and Triple bonds

How does hybridization work with atoms that contain double and triple bonds. Why would a carbon with a triple bond on one atom and a single bond on another have a hybridization of sp?

Re: Nitrogen hybridization

Nitrogen doesn't need to promote any of its electrons from an s-orbital to a p-orbital since there are already three unpaired p-orbital electrons ready to bond. The two valence electrons in the s-orbital are therefore attached to the nitrogen as a lone pair.

Re: 4.33

Yes. The coefficient is necessary since it describes the number of orbitals available for hybridization. For example, sp^2 will have three orbitals available while sp^3 will have four orbitals available. This is a mixture of orbital energy, creating the hybridization.

Re: Order of Orbitals

Usually it doesn't matter, but I know Professor Lavelle wants us to label it in order of increasing n (shell). So you should write it as 3d10 4s2 on all tests and midterms.

Re: What is the extent of elements for the photoelectric effect?

According to Dr. Lavelle, a photoelectric experiment can be done with a non metal, it will just have to be altered to fit that certain substance. However, it's much easier to carry out this experiment on metals, and since it led to many scientific discoveries, Dr. Lavelle goes into detail there the ...

In class today (10/16), Dr. Lavelle confirmed that the cut off is at 10^-15. Anything smaller than that is undetectable and has no wavelike properties.
