To all students sitting for the GCE ‘O’ Level Chemistry Papers in?27?days?time, all the best!
Over the last few months, we have helped students that wants to improve their Chemistry grades by conducting Programmes such as:
- Small Group Essential Concepts Class
- Chemistry Intensive Revision Bootcamps
- Series of Chemistry Mastery Workshops
GCE ‘O’ Level Chemistry Exams will commence in 27 days time.?Are you?looking for?a proven system to Improve Your Chemistry Grades exponentially in a short period? Yes. You can do that, but it requires your 100% Commitment, 150% Participation and 200% DESIRE TO SCORE LIKE A WINNER!
Here is what i have for committed students:
A Final Chemistry Revision Programme especially catered?for Singapore students (Programme will be held in Singapore) who still have not scored what you deserved.
If you have failed your Chemistry Prelims or have never passed your Chemistry before?despite many?tuition classes or school lessons, this will be your last chance to score the marks you truly deserve.
Here’s what GCE ‘O’ Level Chemistry Final Leap Programme will do for you:
- Equip you with the Essential Chemistry concepts using Accelerated Learning Techniques & Association Strategies so that you can understand better and retain more during this short period of time
- Expose you to the Secrets of Lnking Concepts on examination questions so that you can Score!
- Help you to Regain the Confidence required to fight the Chemistry examination victoriously
- Shock you on how you can Score in Chemistry easily?just by Applying?Step-by-Step Strategies
All based on real GCE ‘O’ Level exam-based questions.
Here’s what I want you to do next:

Hi Ahsan,
Thanks for your message.
Alot of O-Level students who came to us have this problem too. They either mentioned that they couldn’t finish their exam papers in time or left alot of blanks at the front.
Now, first of all, do understand that ALL examination papers are set fairly in terms of time allocation. Students should have enough time to finish the paper. For some, they even have some available time to check on questions which they are not confident of.
Next, in order to master Chemistry and thus always have ample time to finish your Chemistry papers, you need to:
(1) Understand all the essential concepts (and not simply by memorising the facts in the O-Level Chemistry notes or O-Level Chemistry textbooks)
(2) Know all the associated keywords and equations relevant to each essential concept (remember that examiners mark you based on keywords and key reaction equations)
(3) Be flexible enough to apply your (1) and (2) above on new scenarios each time.
Obviously, (1) is most important. If you do not know your concepts well enough, you will not be able to master Chemistry.
Hope you find the above info useful to your Chemistry learning.
To Your Chemistry Success,

I am having problem in solving chemistry past papers questions ….they r really lenghty…
Can u plz guide me how to solve past papers effectively?
I am an Olevel student
thnx for encouraging
Thanks for the encouragement!
Hope you are doing well. Keep Learning!
I’ve indeed benefit from your blogs. Presently, am writing the ongoing GCE O’level. Am actually a Nigerian and am indeed grateful to you. Especially for owning a wonderful site like this and for being there to help people like us who see chemistry as a subject difficult to comprehend. I really don’t have much to say rather than praising you for a job well done. Though I still encounter difficulty in some areas. Thanks once again.
Hi Jennifer,
This question is testing you on your application of the basic concepts that you should have leanred in Organic Chemistry chapters.
The last two alkanes should be very very long. Personally i have only heard of this long chain why i was working with Dr. Wu Jishan from NUS-Dept of Chemistry. I read and understand that he has been researching on the many special properties of Pentacontane.
http://www.chemistry.nus.edu.sg/ourpeople/_files/Full%20Publications%20List-wu%20js.pdf
But you dont need all the tough chemistry to predict the boiling points of Pentacontane.
Based on the basic essential concepts that i have taught you in June’s Chemistry Intensive Revision Bootcamp, we know that boiling points are affected by the weak Van der Waals forces of attraction holding covalent molecules together.
Pentacontane is an alkane and thus a covalent molcule. For covalent molecules, the greater the chain length for molecule, the larger the amount of many weak Van der Waals forces acting between many molecules. As such, more heat energy is required to break the Van der Waals forces, before the molecules can break free and become gaseous. This means boiling points increases.
If question ask: “Why there is no boiling points for Pentacontane?”, then the answer must be around the fact that Pentacontane is a very long alkane molecule and they are too many Van der Waals forces acting between those molecules. This prevent the molecules to change from liquid state to gaseous state. Thus, no boiling points for Pentacontane.
PS: Pentacontane is a long alkane molecule made up of 50 Carbon atoms.
This applies to tetrachontane also.
Hope this explanation is useful to you!

Hey there Sean.
heres a question that i need your help.
Suggests two reasons why there are no values given for the boiling points of the last 2 alkanes, tetrachontane and pentacontane.
Thanks Sean.
Hi James,
I am glad you love this chemistry blog-site.

Hi, I found your blog on this new directory of WordPress Blogs at blackhatbootcamp.com/listofwordpressblogs. I dont know how your blog came up, must have been a typo, i duno. Anyways, I just clicked it and here I am. Your blog looks good. Have a nice day. James.
