Notice of Next Lesson & Solutions to Arenes Practice

posted Dec 20, 2016, 10:47 PM by Grace Ong

Dear Students,

Please note that our lesson at Thinking-Learning Centre will resume on Sunday, 8 Jan 2017.

In the meantime, you may wish to recap (Sidebar: FOR MY STUDENTS ... \ Lesson Recap) on what we have covered thus far on Arenes to consolidate your learning.

I have also uploaded solutions to selected questions on areas we have discussed the last two lessons. These solutions are filed under Extension Topics \ Organic Chemistry \ 03. Hydrocarbons (Alkanes, Alkenes & Arenes).

Dear students,
  1. Please find the above solutions under Extension Topics \ Organic Chemistry \ 01. Introduction.

  2. Note that it is not a requirement to draw the cyclic halonium intermediate for electrophilic addition mechanisms involving halogens. The open carbocation intermediate, which is simpler to draw, will also accepted be by Cambridge examiners.

Year-End Holiday Lessons

Dear students,

Our lessons at Thinking Learning Centre will resume on Sunday, 23 October 2016.

So that everyone starts on the same baseline, I will begin with the topics of hybridisation and alkene chemistry, before I proceed with the other Organic Chemistry topics like Arenes, Halogenoalkanes and Hydroxy Compounds.

I will also re-visit the free-radical substitution (FRS) mechanism again so that I may explain, in greater detail, the arrow or electron pushing diagrams for the FRS which you are expected to use. An example of such diagrams is found in the Alkanes practice solutions which I uploaded to the Extension Topics \ Organic Chemistry file cabinet.
