I have the same question but based on what I saw in class today, I think your explanation is correct. The chair conformation in cyclohexane is a very good example of this- watch the conformation of it and it'll be apparent :) Here is a link for the example of cyclohexane: http://www.chem.uiuc.edu/we...

https://www.stolaf.edu/depts/chemistry/courses/toolkits/247/js/names/dnames.htm Honestly this link has SO MANY line structure practice questions- you just keep generating! Also helps with analyzing and gives ALL potential names and why the correct one is correct. So if you're asked for naming from a...

Substituents are groups that replace a certain atom or molecule at a specific position. The example I written down is of the methyl group (notice the suffix of -yl). Methyl has a chemical formula of CH3. I think you add the alkyl group if you remove the hydrogen, drop the -ane suffix and replace it ...

I think kinetics is the study of the rate of reactions, while thermodynamics helps track the heat, internal energy, entropy, gibbs free energy etc of the system in question. We will probably see a more evident connection between organic chemistry and thermodynamics as the chapter progresses: but it ...

I believe the number of orders is based off the number of substance you have. This would mean a reaction with three chemicals is third order. Still, I am confused too. Please clarify...I found this on the internet "order of reaction with respect to a given substance (such as reactant, catalyst ...

Catalysts can also lower the overall activation energy needed to begin a reaction. This is more from a biological standpoint, but it still is the same concept: catalysts can aid a reaction in starting with lower energy or help the reaction speed up. I think this would translate into a graph by where...

Yes but one thing that also strikes me is why specifically Platinum, and not gold or copper? Would it not make sense that a lot of wires and communication vectors use Cu as a material? Just thought about this since my iphone and laptop cable seems to Cu inside!

This is simply the second law of thermodynamics: how heat flows naturally from an object at higher temperature to an object at lower temperature. You need work to force the heat in the other direction (this is what Air Conditioner and Refrigerators do). I agree with the example stated above: it real...

I don't think the KJ value is equally divided by the atoms or molecules, so you can't just go through and divide. You must manipulate the reactants and products and reverse positive and negative signs depending on if you moved products and reactants on opposite sides.

Adding onto the topic of sublimation, when we calculate the phase change reaction of sublimation, do we only calculate vapor and solid changes? Or do we follow the line of phase change, including the liquid part? I remember the TA saying we always have to calculate ALL steps in between (that we cant...

Don't trust atoms, they make up everything.

Some people find chemistry jokes funny...I find them prephosphorous!

Alumnium oxide splits and the oxygen accepts a proton which then forms water. Aluminium oxide is an acid because it reacts with a base to form a salt and water which happens during a neutralization reaction...someone correct me if I'm wrong?

Are you made of Fluorine, Iodine, and Neon?

Because you are FINe ;).

One thing I believe I have correct is that cis forms are polar and trans forms are non polar. This can be important when talking about trans fats and other variations of biological compounds.

I have the same questions too, about this concept covered in lecture.

What do chemists call a benzene ring with iron atoms replacing the carbon atoms?
A ferrous wheel!

What do you do with a sick chemist?
First you try to helium, then you try to curium, but if this fails then you have to barium.

To my knowledge, the goal is to get at least the central atom to a FC of 0. The rest should be "balanced" to the best you can, meaning one side of the atom shouldn't have an excessive charge compared to the other atoms. This is one issue that my friends and I were discussing when we got to...

Hi All,

I remember it was said in lecture that this is the first time change in energy is not final-initial.

The course reader mentions E= E(X)(g)-E(X-)(g). Is this neutral minus the ion? Overall, I'm just confused on why and how the final minus initial concept doesn't apply here.

There also are two series that were mentioned in the course reader (Balmer and Lyman). These are two series on the emissions spectra. I believe we don't have to know exact values for these series, but the names stemmed from the machinery and labs that they were discovered/recorded. Just thought this...

The idea that light is dual in nature can actually work to our advantage at times: if one equation does not work, then we can try the other. That also will shed new perspective on the homework problem (at least from my experience). After attending lecture, understanding that light is dual in nature ...
