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.

A Level Chemistry 2017 Paper 1 Question 23 Solution - Exclusive

In this exclusive video we want to discuss the suggested solution for A Levels Chemistry (H2 Chemistry) 2017 Paper 1 Question 23.

Let Chemistry Guru, Singapore's top JC Chemistry tuition centre, guide you through this question:

2017 A Level H2 Chemistry P1 Q23 question

The concept tested in this question is on the reactivity of C-X bonds in Halogenoalkanes.

For a list of all the reactions of halogenalkanes, do check out this video lesson.

When silver nitrate is used in organic chemistry questions, we are testing for the presence of sliver halide precipitates, where the halides are released from nucleophilic substitution reactions of halogenoalkanes or alkylhalides.

Observation 1 - No precipitate formed in 2 of the tubes

When no precipitate is formed, it means the C-X bond is stable and resistant to nucleophilic substitution.

Halogenobenzene will give this observation as the lone pair of halogen can interact with the delocalised pi system of benzene and the C-X bond is stablised by resonance which makes it unreactive.
