Grade 11 Chemistry – Friday/Monday

Standard Level has study hall.  Remember that you are working on the revision guide I sent you. Help each other!

Higher level needs to continue on with …

Elimination Reactions

Watch both videos explaining what elimination reactions are and the mechanism by which the progress.

You now have a complete set of reactions from the higher level material.  Below is a concept map of the the reactions you have learnt just in higher level.  It is very blank.  Copy and annotate the diagram with:

  1. reagents used
  2. conditions for the reactions
  3. examples of the functional groups you are making or using.

When I get back, we will continue with the final part of the topic which is stereoisomerism.  More model building for us!

Until then, try the following past paper questions.  Ignore anything that talks about geometric isomerism, cis/trans or chiral compounds.  We will do that next week.

If you are having trouble with the questions above, you may also like to revise part one of the SL material.

Grade 12 – Thursday and Friday

Dissolved Oxygen in Water

  1. Read pg 451 and 452 from the text.
  2. Take your own notes on BOD, aerobic and anaerobic decomposition, eutrophication and thermal pollution.

Water Treatment

  1. Watch the video.  Make notes on the different stages of water treatment.
  2. Read pg 452 to 455 from the text and add to your notes from the video as necessary.

Practice

Revise the information we have covered so far on air pollution, acid deposition, greenhouse effect and ozone depletion.

You can now answer most of the questions from SL except those on soil and waste.  As always HL still has a way to go!

SL Organic Review – Part 1

Here is the review of this topic for SL.  HL students should also take a look at this before reviewing the HL only material.

Introduction to Organic Chemistry

In this section, you will review the following syllabus points:

At the end of it, you should be able to:

  1. Define a homologous series – put this definition on your definitions page!
  2. Use your knowledge about intermolecular forces (from the Bonding topic), to predict which compounds will have higher boiling points.
  3. Understand the difference between a molecular, structural and empirical formula.
  4. Describe and recognise structural isomers with the same molecular formula.
  5. Use your knowledge of polar and non-polar compounds and intermolecular forces (both from the Bonding topic) to discuss the volatility and water solubility of organic compounds.

How to review

  1. First of all, make a note of any of the points above you are not sure of.
  2. Review your notes from class.
  3. Have a look at one or all of the videos that specifically address these points.

Organic Nomenclature

In this section you will learn to name and draw the structural formulas of different organic compounds.  You will review the following syllabus points:

After reviewing this section, you should be able to:

  1.  name and draw alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids and alkyl halides
  2. recognise (but not name) amines (amino groups), benzene rings and esters
  3. identify primary, secondary and tertiary alcohols and alkyl halides.

How to review

  1. Note any of the above functional groups that you can’t recognise and/or name.
  2. Review your notes from class
  3. Make flashcards or use a program like Quizlet that has them already made for you!
  4. Learn them!
  5. Use the videos below to help you if you aren’t sure which compound is which or how to name them.

Alkanes

In this section, you will learn about the reactivity and reactions of alkanes.   You will review the following syllabus points.

Screen Shot 2014-03-02 at 7.38.12 PM

 

After reviewing this section, you should be able to:

  1. Explain why alkanes are relatively unreactive.
  2. Write equations for the complete and incomplete combustion of alkanes.
  3. Write equations for the reaction of alkanes with a halogen.
  4. Write the free radical mechanism for the reaction of methane or ethane with either chlorine or bromine.

How to review

  1. Review your notes from class.
  2. For the free radical mechanism, you will only need to be able to write it for methane or ethane.  Learn them.  It follows a pattern.
  3. Check out these videos if you are completely stuck.

After reviewing this section, you should be able to:

  1. Write equations for addition reactions between alkenes and halogens, hydrogen, water and hydrogen halides.
  2. Describe with equations and observations the test for distinguishing between alkanes and alkenes.
  3. Draw sections of addition polymers given the monomer and vice versa.
  4. Say why alkenes are important.

How to review

  1. Review your notes from class, including notes in your lab book and experiments we’ve done with alkanes and alkenes.
  2. Use the videos to help if you get stuck.

Putting Part 1 All Together

If you are still unclear on any of the points above, DO NOT proceed to this section.

Seek help from:

  • a class member
  • another class member
  • any grade 11 chem student whose name begins with K
  • any grade 12 chem student whose name begins with K
  • one of the IB chemistry web pages
  • post your question on our community and see if anyone can help
  • post your question on an ib chemistry forum on one of the ib chem pages
  • post your question on twitter #ibchem
  • Google it!

Once you are satisfied that you get everything, then, and only then, try the following more difficult questions.

Many of the questions are similar, so if you get one wrong, study the answer until you understand it, and then try another similar question the next day.
