CHEMISTRY 353 TUTORIAL / CAL ASSIGNMENTS WINTER 2024 Last modified:

TROUBLESHOOTING? (Plugins needed etc)

• There will be five graded assignments of equal weight for completion in Chem 353.
• Details on the current proposed dates and content of each assignment are provided below.
• You should always assume that the coverage is cumulative (i.e. content from a previous assignment is expected in later assignments).
• These assignments must be completed in your registered tutorial time in SA204 during the week specified.
• Assignments are expected to be written under exam conditions.
• All the assignments have a 50 minute time limit.

"Exam conditions" means that you will be allowed to use a calculator and/or model kit and have access to a periodic table and spectroscopy data tables if required. Absolutely no other resources can be used while completing an assignment. These are the same resources that are allowed in examinations. It also means, that like examinations, you are not allowed to interact in any way with another student while completing the assignment. Anyone found breaking these rules will be reported as academic misconduct.

If you have any doubt as to the interpretation of the statement about "exam conditions" ask your instructor or the course coordinator before taking a risk!

The questions in the assignments will be of a similar type to those of Chem 351/3 examinations and the practice problems we will be providing for discussion during the course etc. This could include synthesis problems and structure determination problems.

• If you for some reason cannot attend an assignment week, please complete the linked form to request an alternate time or request an excused absence.
  
• Once you have submited the form, wait for it to be processed (allow at least one business day), there is normally no need to send a follow email.
• Only legitimate reasons for missing your assignment will be considered for a makeup tutorial (i.e. excuses from the past like "it was my birthday" or "I needed to help do yardwork", will not give you a makeup or excused absence).
• Make up tutorial assignments must be rescheduled within the assignment week between Tuesday-Thursday when 353 CAL tutorials take place (as per the form).
• In cases where it is not possible to do a makeup tutorial assignment for a legitimate reason, the grade for that assignment will be given the same score as the score on the final examination, as outlined in the course outline.

If you have any further queries about these assignments, please contact the CAL coordinator, Dr Ian Hunt.

• Review the course website, especially laboratory materials, the weekly bulletin etc.
• Get logged in to Moodle (follow the instructions on the link very carefully)
• Once into the Moodle Chem 353 W24 course, review the document that describes how Moodle works and some key features.
• Complete the Moodle Usage Policy (100% score required)
• Review the JSME drawing tool video in D2L then work through the "Organic Structure Drawing Tool 101" training exercise in Moodle (it is not for coursemarks, it trains you to use the tool which is an important part of the CAL materials : D2L Chem353W24, Content, Tutorials).
• When you finish, that you should start the review / preparation for the first assignment CAL353.A1 (see below).

Chem 353.A1 : To be completed in SA204 during your scheduled tutorial time Wk3, Jan 22-26 2024.

Assignment 1 : "Chem351 review" is based on ALL Chem 351 materials. In particular, it will cover reactions involving alcohols and alkyl halides and spectroscopy. In order to be ready to complete the assignment, you should work through the linked CAL materials and / or the appropriate material from the course textbook as you require. Practice material self assessments 351.4a-c and 351.5a-b are particularly recommended as preparation for this assignment.

• Spectroscopy (MS, IR, NMR) (Ch13)
• Nucleophilic substitution reactions SN1 and SN2 of alcohols and alkyl halides and their derivatives. (Ch 4 and Ch8)
• Elimination reactions E1 and E2 of alcohols and alkyl halides and their derivatives. (Ch 5)
• Radical substitution reactions. (Ch 4)

Links to important reaction materials in the Organic Chemistry On-Line Learning Center (but you should look at Ch4, Ch8 and Ch5 for the more general issues)

• Properties of Alcohols, Alkyl halides, and Alkenes
• Nucleophilic Substitution reactions
• Nucleophiles, Leaving Groups, Carbocations
• SN1 and SN2 reactions
• Nucleophilic substituion reactions of alkyl halides and alcohols
• Radical Substitution reactions
• Elimination reactions
• E1 and E2 reactions
• Elimination reactions of alkyl halides and alcohols
  

Chem353.A2 : To be completed in SA204 during your scheduled tutorial time, Wk5, Feb 5-9 2024.

Assignment 2 is based on the chemistry of alkenes and alkynes I. This could include properties, preparations, reactions of and spectroscopy.

In order to be ready to complete the assignment, you should work through lecture materials / the linked CAL materials and / or the appropriate material from the course textbook as you require. Practice material Moodle self assessment 353.2 is recommended as preparation for this assignment.

• Preparations of alkenes and alkynes using elimination reactions (Ch 5, Ch 6 and Ch 9)
• Reactions of alkenes and alkynes (Ch 6 and Ch 9)
• Structure & bonding, properties, spectroscopy and reactions from Chem 351 (see Chem 353.A1 above)

Chem353.A3 : To be completed in SA204 during your scheduled tutorial time, Wk7, Feb 26 - Mar 1 2024.

Assignment 3 is based on the chemistry of alkenes and alkynes II. This could include properties, preparations, reactions of and spectroscopy.

In order to be ready to complete the assignment, you should work through lecture materials / the linked CAL materials and / or the appropriate material from the course textbook as you require. Practice material Moodle self assessment 353.3 is recommended as preparation for this assignment.

• Preparations of alkenes and alkynes using elimination reactions (Ch 5, Ch 6 and Ch 9)
• Reactions of alkenes and alkynes (Ch 6 and Ch 9), and epoxides (Ch16) (since they can be viewed as a derivative of alkenes)
• Reactions from Chem 351 (see Chem 353.A1 above)
• The content of Chem 353.A2, see above, plus

Chem353.A4 : To be completed in SA204 during your scheduled tutorial time, Wk 11, Mar 25-29 2024

Assignment 4 is based on the chemistry of conjugated systems : dienes, polyenes and aromatic systems. This will include properties, preparations, reactions of and their spectroscopy.

In order to be ready to complete the assignment, you should work through lecture materials / the linked CAL materials and / or the appropriate material from the course textbook as you require. Practice material self assessments 353.4a (polyenes) and 353.4b (aromatics) are recommended as preparation for this assignment.

Chem353.A5 : To be completed in SA204 during your scheduled tutorial time Wk12, April 2-5 2024.

Assignment 5 is based on the chemistry of epoxides and carbonyl compounds including properties, preparations, reactions of and spectroscopy. It covers the chemistry of epoxides (nucleophilic substitution) aldehydes and ketones (nucleophilic addition reactions) and as enolates, and the chemistry of carboxylic acids and their derivatives (nucleophilic acyl substitution). It is based on materials from  Chapter 17 (Aldehydes and Ketones), Chapter 19 (Carboxylic Acids), Chapter 20 (Carboxylic Acid Derivatives) of the etext but will require an understanding of organometallic reagents, Chapter 14 and epoxides.

In order to be ready to complete the assignment, you should work through lecture materials / the linked CAL materials and / or the appropriate material from the course textbook as you require. Practice material self assessments 353.5a and 353.5b are recommended as preparation for this assignment. (links are provided to materials in the Organic Chemistry On-Line etext)
