Dearest students,

Thank you for attending the Chem 351 Midterm Prep Course hosted by Prep101.

Lecture Slides from November 5th

If you attended the lecture but did not receive an email by midnight, November 5th,  e-mail me and I will reply.

The online textbook is such a great resource that you practically don’t need a book for the course.

To start, you will want to learn nomenclature. The Chem 351 site has an excellent nomenclature tool that is interactive and even tells you what you’re doing right and wrong!

Organic Chemistry is not the hard course people make it out to be – It is simply the application of principles learned in Chem 201 (Electronegativity, Electron Density, Structure and Bonding).

You can always search the Carey/UofC website by typing this into google:

site: [Search Term]

Where [Search Term] is literally the concept you want to find. Note that this method works with any website – all you do is point google to the root folder (e.g. /Carey5th/) and you can search wherever.

If you are studying at the UofC, you can check out ALL of their past Organic Chem exams online with fully worked solutions!

  • Please realize the course coordinator has made worked solutions for all exams – just go to that exam’s specific page and click the links to the right of the multiple choice answers. So check those before emailing.

In most university courses. the majority of your marks are in the final and midterm. I recommend you study for your course by learning a topic and then practicing not only from the online textbook but also specific exam sections related to that topic.

Every exam in Chem 351 is organized by section – so download 3 to 4 of the NEWEST exams (The curriculum has changed a bit over 10 years) and hammer the specific section you’re trying to master. Also – print out the tests and write all over them – you memorize and learn much better when you write things down!

If you feel there are any errors or corrections feel free to email me. Most of this work has been checked multiple times but I still like feedback/questions. Thank you!

Extra Notes:

Relative Yield notes. NOTE – when looking at old exams, it doesn’t look like Chlorine Selectivity Factors will be tested on the midterm (they will be on the final – see the pdf).
However, still know that if you’re adding Bromine, it will just go preferentially to the most stable radial position (Tertiary).

How multiple choice works on the Chem 351 exam:

For nomenclature, you need only answer 7 of 8 questions.

Only answer the 7 that you know you will get right.

If you answer 1 through 8 and you get 7 wrong, you will be marked on 1 through 7 and your mark is 6/7 (meaning question 8 doesn’t even get counted).
If you answer 1 through 6 and then 8 (skipping question 7), you get 7/7.
Doing extra work does not get you an extra mark, and in fact you can lose marks.


Slide 75 of Chem 351 Lecture Slides should say 4-methylpent-2-yne not 4-methylbut-2-yne.

Feel free to email anything you have trouble with.
