Re: torsional strain vs steric strain

Torsional Strain is the result of bonds on adjacent atoms being eclipsed. Steric Strain is when atoms or atom groups repel each other because they are unable to occupy the same location. This is straight out of the o-chem textbook.

We don't need to know what has priority.

Re: Cyclopentane Naming

The isopropyl should be 2 because it would give the lowest number combination. 1,1,2 is less than 1,2,2.

Re: Question from midterm

The question asks for the change in volume of the system. The system, as put in the question, consists of two glass vessels each with a volume of 0.24 L.

The quiz just covers kinetics. So from 15.1 to 15.11 or from the beginning of kinetics in the Course Reader to page 73.

Re: Heat of Combustion

You can use Hess' law for the combustion reaction just as you would use it for the enthalpy of formation to find out whatever you are looking for.

Re: 14.29

Transition metal cations are usually aqueous, so it's safe to assume that Ti 3+ and Ti 2+ are aqueous.

I couldn't find anything under the chapter 8 or chapter 9 objectives that says you need to know it, so I think you're good.

Re: Degeneracy

Degeneracy refers to the number of states a system can be in. The higher the degeneracy, the higher the entropy.

Re: Hess' Law Problem #8.61

By flipping the first and second equations, you allow yourself to later get rid of the products/reactants that are not needed in the final equation through the process of cancellation. If you do the cancellation correctly, you should end up with the final equation.
