Module 2 Alcohols, halogenoalkanes and analysis
... Halogenoalkanes are important starting materials for many synthetic routes. This is because they are readily converted into alcohols and other functional groups – you will become familiar with many of these compounds during your Advanced level work. For centuries, alcohols have been widely known and ...
