What is the difference between the unique rate of reaction and just the reaction rate? Also, how would you calculate the unique rate of reaction?

Rebecca_Arnold_3I

Ok thank you!
So if one carbon had fewer hydrogens attached to it, the H from the HBr would attach to the carbon with lesser hydrogens?

Rebecca_Arnold_3I

In the reaction CH3CH=CHCH3 + HBr does it matter on which side the Hydrogen attaches to first? I know that it attaches to one of the Carbons that is involved with the double bond, but does it matter which Carbon?

So I know that the eclipsed conformation is higher in energy than the staggered conformation. However, I am not completely sure on why this is. Is it because the C-H bonds for the eclipsed conformation are closer together?

Rebecca_Arnold_3I

If a cyclopentane has one isopropyl on one Carbon and two methyl groups both attached to the Carbon right next to it, how would you know which to number first? Would the isopropyl group be numbered as 1 or would the two methyl groups be 1?

If an alcohol has a double bond between two carbons and has 3 carbons in its longest chain, would it be propenol instead of propanol?
Is it possible to have a double bond in an alcohol?

Rebecca_Arnold_3I

Number the Carbons so that the substituents are attached to the lowest numbered Carbon possible.

Rebecca_Arnold_3I

Oh I see!
Thank you so much :)

Catalysts can be included in the rate law!
I'm not sure on whether or not they affect the order of the reaction though.

I'm a little confused on the difference between tert- and iso- butyl.
What is the reason that one substituent is named tert-butyl while another is named iso-butyl?

I know that reaction orders of 3+ or rare because it's hard for three molecules to collide at the same time with the same energy to react.
I'm a little confused on 0 order, though. Does this rate order have to do with the collision of molecules as well? How many molecules collide here?

Hello!
When solving the equation Delta G = delta G (standard) + RT ln(Q), are you allowed to mix concentrations and pressures of the reactants and products depending on which values are given to get Q? Or can only one type be used throughout the Q expression?

Also, stronger acids will generally have a greater number of oxygens. For example in number 2- HCl02 will be a stronger acid than HClO.

I noticed that oxygen and sulfur have two electron affinity values. One is positive, whereas the other is very negative. Why is this? Do the values correspond to the first and second values of electron affinity when more than one electron is added?

Rebecca_Arnold_3I

Yes, it is referring to the name of the ligands and you would write ammine before aqua because of this alphabetical order. I'm not sure about whether or not it matters if you are writing the formula though...

What is the difference between the equivalence and end point of a titration curve? I know that the equivalence point is where the moles of acid = the moles of base, but I'm not sure about an end point. Thank you!!

Rebecca_Arnold_3I

Is it true that when the pressure increases, the volume decreases? If this is the case and the pressure of the reaction increases- why does the reaction favor the side with fewer moles of gas and try to move towards that? Thank you!!

So the neutral ligand amine is NH3. However, the ligand ethylenediamine has NH2 on either end instead of NH3. Why is this the case? Thank you so much!

Rebecca_Arnold_3I

When a ligand is a compound, is the coordination number affected by the number of bonds in this compound, or does the coordination number only apply to the bonds that are directly bonded to the central atom? Thank you!

Rebecca_Arnold_3I

I know that there is a rough guideline for the electronegativity differences in atoms that can be used to determine whether a compound has an ionic or covalent bond. Is there a rough cutoff for when a compound is polar covalent vs. nonpolar covalent? If yes, what is this electronegativity difference...

Rebecca_Arnold_3I

That makes sense, thank you!!

Rebecca_Arnold_3I

In my high school chemistry class, I learned that, along with H, He, Li, and Be, Boron also had an octet exception. I remember that it can have 6 ve-, but I don't understand why this is the case. Why would Boron be happier with 6ve- and not either 2ve-(like H, He, Li, Be) or 8ve-(complying with the ...

Rebecca_Arnold_3I

Thank you, this was very helpful!

Rebecca_Arnold_3I

I'm a little confused about the difference between the Balmer and Lyman Series. I know that they both apply to the Hydrogen atom and that the Balmer series is for the visible region whereas the Lyman series is for the UV region. Is this the only difference between them?
Thank you so much!
