Cycloalkanes as substituents

We didn't really cover this much in class, but it was mentioned that cycloalkanes can be considered substituents if they are part of a main chain that has more carbons than they do.

I was wondering where they fall in terms of priority relative to other substituents, in the case where this occurs.

In the high school review material, the derivation of the ideal gas law is shown, as well as what each variable represents. However, I was wondering whether we need to know about the gas laws that make up the Ideal Gas Law, such as Charles's Law or Boyle's Law, for Quiz 3 or the final.

So I understand why a double bond has one pi bond and one sigma bond. But why does a triple bond have only one sigma bond and 2 pi bonds? Why doesn't it have 2 sigma bonds as well?

Thanks for the response! I understand this, but something else has been bothering me. Why does this only occur in the 4s and 3d orbitals and not afterwards?

Potassium and Calcium

So Dr. Lavelle was talking about how K and Ca are unique in that the 4s2 orbitals fill before the 3d orbitals, but that this doesn't apply after element 20 (Calcium). Can anyone explain this? I'm a bit confused on why it works this way, and why this only occurs before element 20.

Yes, this essentially means that the kinetic energy of the electron is equal to zero. For our uses and purposes, you will usually see questions which will specify "an electron with zero kinetic energy" so you know this is the case. Conceptually, however, it is tricky to understand what thi...
