### priority in naming

Can someone tell me the order in highest priority for naming hydrocarbons? For example in lecture Dr. Lavelle said that double bonds have highest priority and then functional groups and then substituents but then you have to take the highest atomic # and the alphabet into account. Can someone organi...

### Common names vs. (iso and neo)

For the quiz/exam, is it preferred to name the substituents by the iso and neo prefixes? Will we have points deducted if we stick to the common names with the numbers included?

### Double/Triple Bonds

In a situation where a bond moves from a single to a double or triple bond, how do we draw that using the double sided and/or single sided arrows?

### Re: Full arrows vs. Half arrows

I would say a good example for half arrows is when you're dealing with radicals with a single electron that can donate or bond with another radical. It can also work well when you're trying to bond H atoms as they are just a single electron donor.

### 2011 midterm Q6 B

When writing the final balanced equation, why did we have to multiply 2 to both Rb and Rb+? is it because of the electrons when you put them together?

### Calculating final temperature of a substance

When you are given the mass at a certain temperature for substance A, then mass at a different temperature for substance B, are those temperatures correlated to each other and work for both substances (as T initial and T final for both?) If not, how do I find the final temperature of substance B??

### Quiz1 Prep Question 11

Given in step 1, it expands adiabatically from 1.00 L to 2.56 L at 1.00 atm.. in step 2, it releases 73 J of heat at 1.00 atm. For Step 2 in the question, It asks to find the final volume of the system as is returns to the original internal energy. The answer key says change in Volume = -2.28 L and ...

### Cis and Trans Dichloroethene

How do we determine the position in which the chlorine atoms are placed? How do we distinguish when they should be on opposite sides of the double bond or when they're on the same side of the double bond?
