I am honoured to be invited by my former teacher to be one of the guest speaker at alma mater for 2009 Motivation Forum for O Levels Graduating Classes.

In fact, this will be the 3rd time that i will be going back to share my experiences and thoughts on approaching their important qualifying exams in October, as well as discuss with them the strategies and tips on how to perform well for their subjects, typically Chemistry and Science.

I look forward to meeting you (i know some of you are subscriber of this blog) on 24th July 2009!

In the previous blgopost we have discussed on 3 MCQ questions on Organic Chemistry that came out in 2008 GCE O Levels Chemistry Exams. Let’s continue with the rest of the MCQ questions that are related to Organic Chemistry.

Question 1: under sub-topic “Carboxylic Acids”

The reaction between a carboxylic acid, CxHyCO2H, and an alcohol, CnH2n+1OH, produces an ester.

How many hydrogen atoms does one molecule of the ester contain?

A.  y + 2n
B.  y + 2n + 1
C.  y + 2n + 2
D.  y + 2n + 3

PS: Tricky question that ALL Pure Chemistry students must know how to answer

Question 2: under sub-topic “Carboxylic Acids” (more…)

Hi Students (and parents),

Thank you for all your email enquries on our annual Organic Chemistry Mastery Workshops 2009 for O Level students.

As mentioned that in 2008 GCE O Levels Chemistry Exams, Organic Chemistry plays a large part of the questions that came out in Paper 1 (Multiple Choice Questions) and 2 (Written).

Today i am going to share with you some of the multiple choice questions that came out. I will help you by directing you to the “sub-topics” of Organic Chemistry that the question is based on:

Question 1: Under sub-topic ” Fuels”

In how many of the following can paraffin (kerosene) be used as the energy source?
