I’ve been meaning to post this notice since last week. Sorry I didn’t get around to it.
You can hand in the ‘take home test’ and assignment on Friday (28’6’13).

To remind you (in case you need reminding)…
Use 3 references to read about the four topics; alcohols, ethers, alkenes and alkynes,
Review the the information you read there.

Obviously you haven’t got must space to do this for every reaction etc, so be selective: Best to choose topics/reactions that you had difficulty with – you can use the ‘skeleton grid’ spreadsheet that I made to list all topics, and then assess which ones you had a problem with.

After reading about these ‘difficult things’ in the three sources, will (hopefully) resolve any problems you might have had with them. You ‘review’ it by commenting on source hekped you understand it better and WHY compared to the other sources…. which sources made things more confusing…. etc. Give a critical analysis.

 

Here’s some Q’s to hopefully help you in the exam. Two (mini)topics only so far I’m afraid… Alkynes and halogenoalkanes.

Will try and upload some more soon. Do make sure to try to give as full ans answer as you can, even if you’re not confident of your answer (which you should be), as that way you learn much more better and know your weaknesses.

Final Exam. Here’s some Mock Exam Q’s to hopefully help you.

Assignment. Try and hand in by 21 June 2013 or earlier. Can give enstinsions if you have a good reason.
You have to choose 3 websites or three books (or a mixture of them) and critically review them on the topics of alcohols, ethers, alkenes and alkynes. You must quote the sources you use. It can be hand written or typed.

Note: This assignment is to be done individually, with no collaboration. You must not copy and paste information. All work must be of your own creation.

2 pages minimum (up to 4 pages max)

Specifically you are to assess these sources as to how good they are in helping you understand the learning requirments of :

ALCOHOLS/ETHERS:
Structure, Nomenclature and Physical Properties
Synthesis of Alcohols from Alkenes
Reactions of Alcohols, Alcohols as Acids;
Conversion to Alkyl Halides;
Oxidation to Carbonyl Compounds
Synthesis and Reactions of Ethers
Phenols: Structure and Nomenclature; Synthesis and Reactions

ALKENES:
Nomenclature, Structure and Physical Properties
Reactions and Mechanisms
Synthesis of Alkenes via Elimination Reactions: Dehydrohalogenation, Dehydration, Debromination
Addition Reactions  and Markovnikov’s and AntiMarkovnikov’s Rule
Oxidation reaction of alkene

ALKYNES:
Nomenclature, Structure and Physical Properties
Reactions and Mechanisms
Addition, Hydration, Oxidation and Reduction

You should also try and give a summary of the relevant or important reactions.

Each source will probably mention something other sources will omit, as well going ‘deep’ into certain reactions. Read about them (of course) but no need to spend too much effort covering ‘off centre’ reactions. Use the reactions listed above and those in the powerpoint slides as your guide – if you need to.

You may like to make a table, like the abbreviated suggested example below, to rate each source according to what you must read. BUT you must still describe in words….

What
a) problems you faced in reading and understanding the material.
b) whether it was helpful
c) What could have been better about it.
d) How easy it was to remember and recall the information later

Obviously you will not be able to do this for ALL reactions, so comment on a selection, possibly ones that you thought were very well presented and what was very difficult. erc.

This is NOT A CHORE. This is an exercise to assist your learning of these topics. You should be doing this stuff anyway – reading books, watching videos and reading websites, so you should already have most of this to hand.

An abbreviated example of how to possibly summarise the review. (I attack the spreadsheet also)

Naturally, the more effort you put into doing this, the more it will help you.
