Functional Groups

Since there are priorities within functional groups, will we have to be aware of these for the exam? If not, then does that mean we will not be a given a problem where there is more than one functional group?

Numbering

For numbering the carbons, you don't sum up the the individual numbers for every substituent right? For example, if you had to choose between 1, 2, 5 and 1, 3, 5 you would choose the first numbering because 2 is less than 3 and not because 8 is less than 9 (which is the sum of both sets respectively)?

15.21

For the solution to this problem, is it possible to use grams/liter to solve for [A] initial? The manual finds the ratio of [A] initial compared to [A] final but I tried using the measurement of mg that was given and still got the same answer.

Re: Pre Equilibrium Approach

Should we know how to use steady-state approaches? The pre equilibrium approach was already discussed in lecture but unless the steady state will be covered later do you advise that we study both?

Finding n

I'm still confused on how to find the number of moles in the formula for Gibbs. Is it the number of electrons that you gain/lose from both the half reactions??

Workbook Quizzes

I'm still a little confused on how this works. So you can do workbook quizzes and turn them in before every quiz throughout the quarter and whichever one receives a higher score is the one that is counted? If so, does that apply to all quizzes or will this only count for one quiz only?

Work Equations

Just to clarify, the difference between the two different types of work equations is that one is for when a system is under constant pressure and the other is if the system is not? Also, why does w=0 when volume is constant?

Bond Enthalpy

For bond enthalpies, would finding the sum of ALL bonds for the products and reactants give you the same result as finding the sum of ONLY the bonds that broke or formed in a reaction?
