Re: Winter 2016 Final Exam Review and Information

Electrolysis is lightly touched on in the course reader. Will there be math problems on electrolysis on the final?

Re: nucleophile and electrophile

Electrophiles have a positive charge and nucleophiles have a negative charge, but there are neutral electrophiles and nucleophiles that can be tricky to identify. Usually the lewis structures of nucleophiles will have one or more lone pairs. Electrophiles can be cations, radicals, or Lewis acids. An...

Re: Organic Naming

For ethers, we always divide the chain into two parts: the chains on either side of the oxygen. The oxygen will always go with the shorter chain which consists of a substituent and since substituents go in the beginning of the name, so does the ether. Yes. The ether is named in the beginning of the ...

Vinyl and allyl groups

Can someone explain what vinyl and allyl groups are and how they are named? What would vinyl chloride look like?

Re: Bicycloalkanes

When naming a line structure for such a bicycloalkane, you start the numbering of the carbon atoms at the bridge where the two cycles meet. In example 1.18, that would be one of the two carbons that is attached to the vertical square/rectangle shape. Then you go in the direction of the longest chain...

Re: Quiz preparation question 5

This must be a typo in the workbook answers because according to the IUPAC rules, numbering should start alphabetically. check this website, it lists all the rules: https://www2.chemistry.msu.edu/faculty/reusch/virttxtjml/nomen1.htm

Relationship between Gibbs free energy and bond dissociation

What is bond dissociation energy? What is Gibbs free energy, what does a delta g value mean? And what is the correlation between the two?

Problem 11.83: Using values from appendix 2a

The problem asks you to calculat K at 25C and 150 C using data in appendix 2a however appendix 2a only gives values at standard temperature not 150 C so why does the solution manual use the values in the appendix for 150 C? Is that valid?

Re: Order of Increasing Change in Entropy

Monatomic gases have more particles because diatomic particles are two monotomic particles stuck together which means that even tho the diatomic gas and monotomic gas have the same number of particles, the particles in the monatomic gas are more detached and diffused, covering more space and moving ...

Re: About spontaneity and boiling point

the vaporization of water is only spontaneous and high temperatures above or at it's boiling point, it is not spontaneous at any other temperatures including room temperature.

Re: Adiabatic Systems

I don't believe you need to know an example of an adiabatic system for the exam, i believe that information will be stated in the problem, if you are worried about how to identify it. Also remember entropy is always 0 in an adiabatic system.
