Re: Direction of arrow in bond breaking

I'm thinking it may be because you want to keep OH together and have it be OH- instead of O- and H+.

Re: Functional Groups

I agree with the above comment. He said himself he won't have two functional groups in one molecules, but in the practice finals, he has them.
I hoping he won't,but I would at least try to remember some of them.

I have always taken snacks to my finals and I have not had a problem with them. I'm pretty sure they will be okay with it.

Re: Q7D. 2011 Winter Final

The figure drawn is 2-methoxy-2 methylpropane not 2-methoxy-1,1 dimethyl ethane Propane, the longest parent chain, is made by the carbon that is completely vertical and the lower left carbon. Methoxy is an oxygen with two carbons attached to it. (C-O-C) which is show to the right of the propane. The...

Re: Ring Strain in Cycloalkenes (Final 2012 Q5)

Cyclo octane has more ring strain because as you add more carbons to a ring it strays away from the preferred 120 degrees.
A cyclo hexane, has less because it has its carbon angles closest to 120 degrees.

Re: Temperature and Activation Energy

Yes, temperature and activation energy are separate of each other. They are independent.

Calculating Energy

When calculating energy, for example for 18 g piece of ice to be raised from -25 C to 125 C, would we convert the energy to J or would we use kJ? How would Professor Lavelle have it on the test/quiz?

Standard Enthalpy

Is the standard enthalpy of the molecular compound always given? Professor Lavelle was discussing about a chart with them and I was wondering if that's how we find them.
