Primary, secondary, tertiary
Do you need to indicate primary, secondary, tertiary, or quaternary when you are naming a molecule with an Amine???

Re: Torsional & Steric Strain
"Torsional Strain: When rotating a molecule around a bond, the torsional strain is the repulsion caused by the electrons in between different groups when they pass by each other. Steric Strain: Strain caused by the electrons in between different groups. Steric strain cannot be lessened by rotat...

Introduction to Organic Chemistry booklet
What will we need to know for the final from the intro to ochem book? For example, bicycloalkanes, spiroalkanes, aromatic hydrocarbons. Will we need to know all of these things?

It works a little better if you sing it out.
Looks like chemistry, but really it is not.

Methyl-Chloro Substituent
If we have a cyclohexane, for example with a methyl substituent on one side and a methyl substituent on the other side that also has chlorine attached to it, would we use the name 1,4-chlorodimethylcyclohexane? Or the name 1-chloromethyl-4-methylcyclohexane.
I hope this question makes sense.

Intensive/Extensive
I am going through previous midterms, and one of them asks if Energy, E, is an intensive or extensive variable.
It was extensive, but why? What is the difference between and intensive and extensive variable?

Re: How many unpaired electrons does the molecule O2 have?
In the textbook, it says that the molecule O2 has 2 unpaired electrons. However, when I draw the Lewis structure (and count the number of valence electrons, which happen to be even), no electrons are unpaired. You must be careful. If they ask for the number of unpaired electrons, they are looking f...

Period Number in Hybridization
When I see hybridization of an element, people sometimes post a period number before. For example, Carbon would be 2sp^3, when it has four bonds. Would it be incorrect to only write sp^3? Is there a right or wrong way?
Thanks!
Thanks!

Re: Orbitals, value of l
Because D is always one below S and P in energy level(n), and F two below, does it mean that the D and F orbitals will never be involved in bonding with any other atoms? If not, what types of bonds would include D and F?
