Trends from 2019 H2 Chemistry Prelim Papers

Hi all,
Some heterocyclic organic compounds containing O, N or S atoms have appeared in 2019 H2 Chemistry Prelim Papers.

So you may wish to read up on lactones, pyrroles or furans only if you have time.

You may search for "lactones" or "furans" or "pyrrole" in wikipedia.

All the best for your examinations!!

New book to recommend

Hi all,
There is a new book in Popular bookshops that is written by Mr Eric Kua. The title is "A Level Chemistry - Novel Organic Chemistry Questions".
Why should you get a copy? It is for those who want to get a pass in your coming Prelims exams and a good grade in A levels Chemistry exams.
What is it about? The guided questions are on novel Chemistry reactions and their mechanisms. These questions are likely to appear in prelims exams in one form or another. The standard of this book is around university year one / two organic chemistry. The author has provided lots of help and clues in the book.

I shall heartily recommend this book.

See ya all and all the best!!

:)
