On page 29 of the Organic Chemistry Textbook, I noticed that when naming organic molecules like methylcyclohexadiene, it can be spelled out with an "a" or without an "a". Which one is right? or When are we supposed to used the A within the name? Meaning: methylcyclohexdiene or me...

I know that we won't be ask for the common names on tests, but I noticed that some (i think IUPAC) names have/utilizes common naming rules, so how do I know if it's IUPAC names or just common names. Also, when do I apply the common naming rules to IUPAC names or how do I know when to ONLY use IUPAC ...

I know Dr.Lavelle tried to explain the organic molecule on page 93 in class, but I'm still confused about the part where he named it 4-Ethyl-2,2-dimethyl-hexane instead of 3-Ethyl-5,5-dimethyl-hexane ? I thought we were supposed to choose the number Carbon that gives the smallest number for the firs...

When integrating (-1/a)d[A]/dt = k[A], why do we assume a is equal to 1?

Does the order matter when you separate molecules of the same state with commas. Do we usually range them in the order of charges? and when we separate gas from aqueous with a solid verticle line, is there a order in which we have to put them in?

I'm a bit confused on when to flip the equations and on which one to flip. I think my TA said that we're suppose to flip the equation to get the highest positive charge when there's two reduction, I just want to confirm this. And also what happens when you have two oxidation equations, which one do ...

Another memorizing tip would be REDCAT, it's recommended by one of the TA's in the midterm review sessions, which stands for
REDuction
occurs
at
CAThodes
and vice versa.
HOPE THIS HELPS!

How does defining the rate at d[A]/dt help us in determining the reaction rate of a reaction? I know it represents the rate of change at a time t, but do we have to integrate it in some way or transform it into another equation?

Jamie Huang 1L

Since change in internal energy is equal to total kinetic energy, and the total E_k is equal to 3/2nRT, i was just wondering in what scenario/problems would we apply this equation, or is this equation simply here for our understanding of the concept.

I was told that we usually get our finals from Chem 14A back around week 3, so I was just wondering if we will be getting our physical test back anytime soon since I haven't heard anyone talking about it. Do we get it during our lecture, from our old TA, or are we supposed to go to a certain place t...

Why is heat not a state property, but enthalpy is considered a state property as it consists of heat?

For the final exam, do we need to know how to calculate the electrostatic potential energy?

Jamie Huang 1L

For example, if you were asked to find the the MO electron configuration, how do you know where do you start from, like from the 1s orbital or the valence orbital?

Jamie Huang 1L

On page 256, in question 2E, I don't quite understand the question and how it links to the answer, which is "orbitals." Can someone explain this to me?

Jamie Huang 1L

When you have a heteronuclear molecule like BF-, where do you add the extra electron ? Is there a specific side where I add/delete electrons? Are we expected to know which side to add/delete them on ?

Does the state of a molecule, paramagnetic or diamagnetic, affects the strength of bonding. When explaining the strength or stability of a molecule, do you ever use their state to explain their strength and stability? Or do you simply use the bond order to explain all of the above?

Jamie Huang 1L

Since we usually find out the ionic and covalent character of a molecule using the electronegativity chart on our course reader, are we given that chart during quizes and tests?

For this question, I got 7.56 x 10^-20 J for when freq is equal to 1.14 x 10^14 Hz, then using n=4, I plugged in -hR/n^2 and I got -1.36 x 10 ^-19 J. When I try to subtract the Energy of n=4 from Energy of freq, I got -2.12 x 10^-19 J. Using this Energy, I try to find n by plugging values into the f...

I would say 2/3 times a week. At least once in the weekend, if people can't make it to the time(s) during the week. As for me, I'm fine with anytime after 6PM during the week.

I live in hedrick hall, and i'm interested too! Let me know when and where to meet ! Thanks !
