Using the 'curly arrow' notation
The aim of this site is to help
students learn about using the 'curly arrow' notation for reaction mechanisms
in organic chemistry. There is an introduction about notation and also about
the role of lone pairs and electronics in mechanisms. There are interactive
questions on a range of mechanisms including nucleophilic substitution,
elimination, alkene reactions, nucleophilic addition to carbonyls and
electrophilic aromatic substitution. Users employ 'drag and drop' to show
electron movement. This will be of great value in post-18 education when used
alongside ordinary texts. The first few examples in each section will also be
of use to candidates following advanced courses post-16 but they may be a
little confused by the use of 'Me' or 'Et' abbreviations.
