Re: Constitutional Isomers
I also try and determine this by first drawing a structure with the longest Carbon chain possible and then drawing structures with one Carbon less each time. So, for example, if the longest chain you can make is 6 Carbons, you first draw a structure with a six carbon parent chain. Then the next stru...

Re: Determining highest-priority groups in isomers
You should also be looking at the groups that are across a double bond.

winter 2011 midterm, question 2B
Can anyone explain why Container A has the highest entropy? Why would a monatomic gas have a higher entropy than a vibrationally active diatomic gas?
Thanks!
Thanks!

cis and trans pg. 805
Can anyone explain why, in diagram 26 on page 805 in the book, the left hand structure is trans and the right hand structure is cis? Thanks!

Changes in Volume
In Lecture on Wednesday we discussed that there can only be a change in volume in a system if a gas is involved in the reaction, and that if a solid or liquid is involved, PdV would be insignificant. Is this assuming that the system is closed/isolated?

Question 8.9
"An ideal gas in a cylinder was placed in a heater and gained 5.50 kJ of energy as heat. If the cylinder increased in volume from 345 mL to 1846 mL against an atmospheric pressure of 750. Torr during this process, what is the change in internal energy of the gas in the cylinder?" How would...
