Paper 2 - Physical, Organic and Class: ________________________
Inorganic Date: ________________________
Time: 2 hours
Marks: 104 marks
Paper 2 is usually Physical and Organic but we
have split these papers up based on what you
have been taught by each teacher.
This paper contains some Physical content to
give questions the structure of a real exam
Comments: rather than chopping and changing questions.
Questions in your actual exams in the
summer will not be 1 topic per question, but
multiple topics from different disciplines
together.
Q1.
This question is about the analysis of organic compounds.
(a) The table below shows the results of chemical tests on three organic
compounds.
Complete the empty boxes in the table.
