Re: Ether naming
You want to find the longest parent chain without regards to the ether. Then when looking at the ether, you want to see how long the rest of the carbon chain not part of the parent chain is. So if it is attached to a chain of three carbons, it would normally be propyl. However, because it is an ethe...
Re: Numbering
Adding on to what Danica said, double bonds do take priority. And when writing the systematic name, you do need to give them the lower number AND make note of that number in the name. You would normally add this before the root part of the name. So if the double bond is at the first carbon on a six ...

Re: Alphabetical order
With the ordering of the substituents, you want to put them in alphabetical order. So if you have ethyl and methyl, you would put ethyl before methyl in the name. Things get a little trickier when you start to use common names instead of the IUPAC names. When you have something with "iso" ...

Re: Single bond vs. Double Bond
Building off of what Katie said, Saturated hydrocarbons are generally solids at room temperature, while unsaturated hydrocarbons are generally liquids at room temperature. The states are important because looking at a saturated hydrocarbon, they are generally solids due to the long chains of single ...

Re: Friedal-Crafts Alkylation
Generally, the bonds that are broken are dependent on the slight polarity created between the atoms. This makes the bond vulnerable and thus it is the most likely to break. You indicate the slight polarity by \delta and its sign. Those elements that are more electronegative, are generally more likel...

Re: Pseudo First Order Reactions
Just building on what Katie said, The goal (as the name implies) is to make a reaction that is dependent on the concentrations of more than one species to appear as a first order reaction. So if you have a second order reaction (such as k[S2O8^(2-)][I-]) then you want to assume that one of them has ...

Pre-Equilibrium Approach to Reaction Mechanisms
I am having trouble understanding the bottle neck affect for a two step reaction. How does the first step being fast and the second step being slow cause the first step to be in "equilibrium". Also, can we still use the pre-equilibrium approach if the first step is slow and the second step...

Electrolysis Cell Potential
Will the cell potential for an electrolysis reaction always be negative?

Re: Galvanic Cell
So, essentially how the galvanic cell works is that it has two electrodes, in this case one with zinc metal and one with copper metal. If we were to look at this at the atomic level, essentially electrons are being transferred from the zinc atoms to the Cu^(2+) atoms in the second electrode. So in o...

Re: Definition of degeneracy and relationship to entropy
So from our course reader it states that degeneracy is "the number of ways of achieving a given energy state." This basically means that there are different configurations and positions (ie number of ways) and these configurations determine the energy state. Gas will have a higher degenera...

Video: Determining Limiting Reactants Review
Hey fellow Chem14A classmates,
Here is a video I made for review on limiting reactants. I do two example problems, so I hope this helps with studying!
