### Re: Winter Practice Final 2015 9B

So do we always give priority to the functional group as opposed to the longest carbon chain?

### Re: Winter Practice Final 2015 9B

would priority always be given to the OH group? I though it was given to the longest carbon chain?

How come in 9B priority is not given to the cyclic structure?

### Winter 2012 Q1B

On question 1B it says that you have to count the heat of cooling the reactants and heating the products, I was wondering if we could have chosen the heat the reactants and cool the products. If we could not do that then why would we have to cool the reactants and heat the products exclusively?

### Re: pH and cell potential

So since the pH increases the pOH decreases and the CONCENTRATION of OH- increases therefore making Q smaller so E is then increasing.

### Secondary Carbons

What exactly make a carbon a secondary carbon, for example of question 8 in the quiz prep 3 it has two secondary carbons couldn't the carbon boned to the CH3 and the (CH3CHCH3) also be a secondary carbon?

### Quiz Prep 2 Winter 2015 #10

We know that this is a second order reactions because of the rate given. I don't know how to prove if it is true or false. I was thinking to plug in the initial and final rates and solving for (t) for both, but I cannot do that because we are not given k. So, how should I prove this?
