Notes for students and teachers
Chemical Storylines
At the end of WM3 on page 109: 1. Instead of Chemical Ideas 13.4 read 13.4 part b, which is available on the Heinemann website. 2. Read Section 13.5 in your Chemical Ideas book which deals with naming and making esters.
Chemical Ideas
1. While doing Chemical Ideas 13.5 there is no need to cover polyesters (page 318) or ester hydrolysis (page 319). These will be covered in Designer Polymers (DP). As a result there is no need to do Problems 4, 6 (parts d & e) or 8 (parts d & e). 2. Add Esters from salicylic acid (page 315). 3. Note that the anhydride reactions on pages 318–319 do not need to be learned. They are to explain activity WM5.1: A preparation of aspirin.
Activities
A revised version of activity WM3 investigates the chemistry of –OH groups. It is available on the Heinemann website.
End of unit test
Question 3 part e is not suitable for the new specification. (This work is now covered in The Polymer Revolution (PR).)

The —OH group in alcohols, phenols and acids, part b
13.4
The hydroxyl group, —OH, can occur in three different environments in organic molecules: G attached to an alkane chain in alcohols, for example CH CH –OH 3 2 ethanol. Alcohols are of three types, primary, secondary and tertiary, according to the position
