Do amines have priority over double or triple bonds?

what exactly does orthogonal to each other mean..?

I think it would be 4,5 giving th slowest number first and then you look at the "m" in dimethylethyl for alphabetical purposes.

If you determine which atom is more electronegative, you will be able to determine where the electron will most likely be attracted to. So you draw the molecule like a lewis structure, but you will be able to see where the electrons are drawn towards.

If looking at the reversed reaction, does the rate depend on the reactants that were the products, or does it still depend on the original reactants?

I think you determine which atoms are being oxidized and which are being reduced, and based off that you can determine the separate half reactions.

What kind of problems require the use of residual entropy?

How do you find the specific heat capacity if only the heat capacity is provided?

When you use the method of using the bond energies, do you add the left side of the equation to the right side, or subtract the right side from the left side?

Here is a video of examples for balancing chemical equations.

Is there a conceptual reason behind this? I understand the rule that with a greater s orbital, the higher acidity of the acid, but why is this exactly?

When naming coordination complexes, is there a difference between for example chloro and chlorido? Because I've seen both and I don't know whether they are used interchangeably or for specific situations

I think the correct way to write oxidation number is to have the + or - before the number, so +3 rather than 3+

I have a really hard tim figuring out the electron configurations for ions. How do you know whether the ion will lose valence electrons from the d orbital first or if it will lose them from the s orbital first. I know there are exceptions to copper and chromium, but how about all of the other d bloc...

Does the shape of a molecule ever have the ability to determine whether the molecule will act as a lewis acid or base?

Hi! Just wanted to share a trick our TA shared with us to determine hybridization. If you have a central atom, lets say in CCl4, C is the central atom, and it is EX4, you can use the "4" to help you determine hybridization: you need as many letters in the hybridization as the number in the...

I'm a little bit confused as to how you determine which resonance structure is the most stable. Do you have to find the formal charge of each specific atom and see how they differ, or do you find the formal charge of the entire molecule and choose the one that's closest to zero? Or is that the same ...

All you do is count the electrons in the specific orbitals. So for Chlorine for example, you see that the firs ts orbital (the top two squares on the periodic table are filled) so you have 1s2, then you see that the second s orbital (Li and Be) is also filled, so you have 2s2, and the 2p orbital is ...

When finding the molecular formula of a compound, why is it necessary to divide all the moles, by the smallest amount of moles?
