Sorry, I'm currently not accepting students.
Please visit Domain of Experts for other recommended Chemistry tutors.

 

I will be busy for the next couple of months moving house (from Tampines to Bedok). I should be able to accept students some time in the 1st few months of 2025. Students can email me now at bedokfunland@yahoo.com to register your interest, and I'll contact you to discuss arrangements as soon as available in 2025. I look forward to helping you with your H2 Chemistry needs!

The BedokFunland JC Advantage (3 examples) :

Here are BedokFunland JC, you'll learn lots of fascinating advanced H2 Chem as well as relevant (ie. helpful for mastering H2 Chem) H3 Chem & Olympiad Chem concepts & skills, not taught to H2 Chem students in Singapore JCs, that will help you understand and master the H2 Chem syllabus better than your peers in school, ie. the BedokFunland JC advantage. The following examples testify to this.



In the recent 2018 A Level H2 Chem Exams, the following question was asked :




How many moles of NaOH(aq) are reacted when one mole of the above molecule is heated under reflux with an excess of NaOH(aq)? Explain.

On Reddit, a H3 Chem student from an elite Singapore JC wrote :




My BedokFunland JC students would know that the hydrolysis of esters (and amides, for that matter) is either acid-catalyzed or base-promoted, but not base-catalyzed (unlike Aldol reactions, for instance). As such, my BedokFunland JC students (being familiar with these and dozens of other useful reaction mechanisms not taught to H2 Chem students in Singapore JCs) would easily arrive at the correct answer for this 2018 A Level H2 Chem Exam question, which is : 1 mole of NaOH(aq) used up for the base-promoted hydrolysis of the ester group, plus another 5 moles of NaOH(aq) used up for the deprotonation of the carboxylic acid group and 4 phenol groups, for a total of 6 moles of NaOH(aq) reacted & used up.

Another question that came out in the same 2018 A Level H2 Chem Exams, was about the optical activity of the stereoisomers of 3,4-dibromohexane :




On the same Reddit page, another H3 Chem student from another elite Singapore JC wrote :



My BedokFunland JC students would know that merely labeling the stereoisomers with the Cahn–Ingold–Prelog priority rules, does not by itself answer the question's requirements about optical activity. For instance, in the amino acid Threonine, the 2S,3R and the 2R,3S stereoisomers are non-superposable mirror images of each other, and are hence optically active enantiomers.



However, in the case of
3,4-dibromohexane, due to an internal plane of symmetry, the 3S,4R and the 3R,4S stereoisomers are superposable mirror images of each other, meaning that they are actually the same molecule, which is hence the optically inactive meso isomer.






Conclusion : my BedokFunland JC students enjoy the benefit of learning and applying advanced H2 Chem knowledge, together with relevant H3 Chem understanding and Olympiad Chem skills,  effectively gaining a deeper mastery of the H2 Chem syllabus, thus giving them a powerful advantage towards an A grade for the H2 Chem A Level Exams, compared to other tuition centers or private tutors (who largely stick to the basic H2 Chem syllabus, repeating what's already taught in Singapore JCs), even when compared to H3 Chem students in Singapore JCs, as seen in the above examples on Reddit.

For Paired (2-Students) Tuition, you must first find your own friend to come with, preferably from the same JC, but it can be your friend now studying in another JC, as long as your personal scheduling is compatible. Both students must always be present together for all tuition sessions.





Ad hoc Fees Table
 
For ad hoc single sessions, fees will be at a slightly different rate from regular students. For J1 students : $200 for ad hoc 1:1 Individual Tuition, or $150 per student for Paired Tuition (you need to find a friend to come with), per each ad hoc 2 hrs session. For J2 students : see table immediately below. Fees have to be paid in cash (not cheque) at the start (not end) of each ad hoc 2 hrs session. Scheduling subject to availability. Please note : for ad hoc Paired Tuition sessions, both students in your group have to go through the same questions being discussed (students take turns to ask your questions) together as a collaborative group. If each student only wants to focus on his/her own question from his/her own JC, please come for ad hoc 1:1 Individual Tuition instead.

& Conditions

1. There is no 'trial session' available. If you wish to only pay for a single session, the fees payable (to be paid in cash at the start of the single session, will come under the ad hoc single sessions system, which is charged at a slightly higher rate. To qualify for the cheapest rate, please pay for 4 sessions upfront (at the start of the 1st session), fees paid out are non-refundable.

2.  Fees must be paid in cash or PayNow or Paylah (not cheque or bank transfer), at the start (not end) of the 1st session, and at the start (not end) of every 4 sessions. Fees paid out are non-refundable. If a student forgets to bring his fees, the session has to be cancelled and rescheduled. Applies to all students, nothing personal.

3.  Students must inform well in advance if there are any schedule changes. If a student fails to turn up for a scheduled session without adequate advance notice, the session is forfeited, and fees are non-refundable. Students must agree to always be contactable and to reply all texts and/or missed calls.

4.  All missed sessions (regardless of reason, eg. school activities, medical appointments, family activities, etc) must be made up as soon as possible, and to be rescheduled in advance whenever possible (eg. bringing forward all affected sessions, eg. due to school exams). Fees are to be paid at the start of every 4 sessions.

5.  For Group (paired) Tuition, all new students need to find their own friend to form a pair to come with. Both members of a pair must attend every session together. If one member of a pair cannot attend a session (eg. medical leave), the session is cancelled and must be made up as soon as possible, by both members of the pair together.



Thank you for accepting these Terms & Conditions, I look forward to helping you with your H2 Chemistry needs!

BedokFunland JC   H2 Chemistry Questions
.



.
.
Qn :-Why did the acid go to the gym?
Ans : Because it wanted to become a buffer solution.
.
Qn :-How can you identify who's the chemist and who's the economist?
Ans : Ask them to pronounce the word "Unionized".


Two chemists go into a bar. The 1st one says "I'll have a glass of H2O."
The 2nd one says "I'll have a glass of H2O too." — and then he died.



A couple of BedokFunland JC original H2 Chem riddles :


CCl4 has a higher boiling point compared to SICl4, despite SiCl4 being the larger molecule. Suggest why.
T
he C-Cl bond is weaker than the Si-Cl bond, despite the C-Cl bond being the shorter bond. Suggest why.

The standard enthalpy change of combustion of magnesium is the same as the standard enthalpy change of formation of magnesium oxide, but the standard enthalpy change of combustion of aluminium is not the same as the standard enthalpy change of formation of aluminium oxide. Suggest why.

The 1st IE of lithium is more endothermic than the 1st IE of sodium, yet the Data Booklet shows that the standard oxidation potential for lithium is more positive than for sodium. Suggest why.

The covalent bond strengths of the halogens increase from iodine to chlorine, but decreases from chlorine to fluorine. Suggest why.

H3PO3 has a larger Ka1 value compared to H3PO4, despite H3PO4 having a larger number of electronegative O atoms. Suggest why.
