What are the different types of JC Chemistry tuition classes available at your centre?

We have 3 modes of learning for students to choose from: weekly physical classes at Bishan; weekly online lessons via Zoom; and on-demand video lessons.

Are you the only Chemistry tutor conducting the classes or do you engage other tutors to do that?

Please be rest assured that I conduct all my classes personally and I do not engage other tutors to teach at my centre.

How well do your students perform after attending your H2 Chemistry tuition classes?

Most of my students showed improvements by at least 3 grades and more than 80% have attained distinction for A Levels. The earlier the students join my classes, the more confident I am in improving their grades.

What is your class size at Bishan?

Usually the class size is around 10 to 12 students. Max class size is 16 pax.

Is there makeup lesson if I miss a class?

Yes makeup lesson is available in the same week subject to availability. If makeup class is not possible, the student can view the recorded video lessons at Google Classroom.

Do you have trial lesson available? How much is it?

Yes we do. Fees for trial lesson are for Bishan class and for Zoom online class.

Does your centre offer O Level chemistry tuition? Do you teach IB / IP chemistry tuition? How about H1 Chemistry?

Chemistry Guru specialises in H2 Chemistry for JC1 and JC2 or IP Year 5 and IP Year 6 students only. Find out all the information about A Level H2 Chemistry and the detailed comparison between H1 and H2 Chemistry. We do not conduct lessons for H1 Chemistry, O Level Chemistry, IB Chemistry or IP Chemistry at IP Year 3 and IP Year 4.

Oxidation of Alkyl Benzene

In this video created by Chemistry Guru, Singapore's leading JC Chemistry tuition centre, we want to discuss the oxidation of alkyl benzene using KMnO₄ in dilute H₂SO₄, heat under reflux.

oxidation of alkylbenzene reaction reagents and conditions

The criteria for alkylbenzene to be oxidised to benzoic acid is the alpha carbon (carbon directly bonded to benzene) must have minimum 1 H.

The observation for this reaction will be the decolourisation of purple KMnO₄ and formation of white precipitate benzoic acid.

In A Level Chemistry Syllabus, the rest of the groups attached to alpha carbon are usually discarded and we do not need to determine what they are oxidised to, unless it is one carbon then it'll be oxidised to CO₂.

Let Chemistry Guru, Singapore's top JC Chemistry tuition centre, guide you through a few examples:
