Re: Entropy in Expansion
I don't think that it would be any different. Because entropy is a state function it is dependent on only the initial and final states and therefore the path taken and work done in the process does not matter.

Re: Double bonds
a functional group would get priority over a double bond.

Re: Alphabetical Naming
The prefixes iso- and neo- are included in alphabetical ordering (for example, isopropyl would be considered as starting with "I") while sec- and tert- are not (for example, tert-butyl would be considered as starting with "B").

Re: Parenthesis around some carbons?
Yes it means that the carbon before the parentheses has two methyl substituents attached to it. The parentheses make it easier to read so you can easily see that they are substituents attached at that carbon and not part of the chain.

Oder with respect to a reactant
Could someone do a quick run-through of the steps needed to find the order of a particular reactant if you're given a table with initial concentrations and reaction rates? I understand that you look for two trials where only the concentration of the desired reactant is changed and the other concentr...

Re: Quiz 2 Preparation Q6
Given the units of the rate constant, you can tell that the reaction is second order. You can then use rate=k[A]^2 to find the initial concentration of the molecule and then use the volume and molecular weight to find the mass of the sample.

bond enthalpies
If during a reaction a carbon-carbon single bond turns into a carbon-carbon double bond, do you need to break the single bond and then form the double bond in order to calculate the change in enthalpy using bond enthalpies? Or just use the enthalpy of forming a double bond and ignore that there was ...

Overall reaction rate
Why is the overall rate of reaction equal to just the rate of the slowest step rather than the sum off the rates of each step?

Re: Chemistry Jokes
Little Willie was a chemist. Little Willie is no more. What he thought was H2O was H2SO4.
