Hi Students (and parents),

Thank you for all your email enquries on our annual Organic Chemistry Mastery Workshops 2009 for O Level students.

As mentioned that in 2008 GCE O Levels Chemistry Exams, Organic Chemistry plays a large part of the questions that came out in Paper 1 (Multiple Choice Questions) and 2 (Written).

Today i am going to share with you some of the multiple choice questions that came out. I will help you by directing you to the “sub-topics” of Organic Chemistry that the question is based on:

2. They are flammable
3. They react with chlorine

A) 1 and 2 only
B) 2 and 3 only
C) 1 and 3 only
D) 1, 2 and 3

1. X dissolves in aqueous sodium hydroxide but Y is insoluble
2. Y burns in excess oxygen to give X and water only
3. Y does not decolourise aqueous bromine

What are gases X and Y respectively?
