Re: Naming [ENDORSED]

Still having trouble with knowing where to start counting the carbons when there is a double bond, any clarification If there is only a double bond in the molecule then you start counting on the side which gives it the lowest number. If there is a functional group and a double bond, then you give t...

I had the same question. In the answer key or point distribution is says 4pt for identifying 4 correct functional groups, so I assumed it would be.

Re: Transition Steps

I believe the dash arrows are only shown during the transition step to indicate what molecule is attaching and which one is leaving.

Re: Switching Chem 14C discussion

My friends say discussion isn't mandatory and you can attend whichever one you'd like in his class.

Re: Strategies for studying for the final

I'm doing the practice finals and the midterms (again) and returning back to the topics/ questions that I had a hard time with. I just re-do the homework questions for that specific topic until I know how to do it well.

Re: Stability of the Formation

The gauche conformation would be more stable. Because the eclipsed has steric interactions and I believe torsional interactions. But when you look at the gauche conformation that is staggered with an angle of 60° versus the eclipsed by H conformation where it is eclipsed but the angle is at 120°, wh...

Re: Help Drawing Newman Projections

It's a bit difficult to explain. First draw 2-methylbutane (4 carbon chains and a CH3 in the second carbon, also draw all of your H molecules attached to the carbons). The C1-C2 refers to where the the molecule would be split for the Newman projection. The first three molecules would be.. so CH3-CH(...

Re: Saying Thank You to Dr. Lavelle

Dear Dr. Lavelle, Thank you for being such an amazing professor! I admit, at the beginning, I was afraid of taking your class because I've always had a hard time understanding chemistry. I was honestly at the point where I thought I was a lost cause when it came to solving anything that had chem in ...

The -ene refers to a double carbon bond, while the 2 refers to the carbon in which the double bond begins. Therefore 2-butene will be c-c=c-c

Another question pertaining to this. Will it be specified if we have to name the compound with the IUPAC name or the common name?

Re: Winter 2015 Midterm Question 2 and 3 D

for every question with bond enthalpies vs enthalpies of formation, will the question specify what they want? The question usually specifies it. The pattern I have encountered is that when they ask for bond enthalpies, they generally come with a table of bonds (H-O, C-C, etc). and when they want en...
