WebJul 12, 2024 · Electrophilic aromatic substitution is a chemical reaction that involves the replacement of an atom in an aromatic molecule with an electrophile. An electrophile is an atom or a molecule that does not contain electrons. It can accept electrons from an electron-rich species. This electrophile can either be a positively charged species or a ...

The first trend to understand is that electron withdrawing groups (EWG’s) dramatically increasethe rate of reaction, not decrease it. From this, it follows that the more … See more Let’s review electrophilic aromatic substitution (EAS). What have we learned? 1.

(But, as you may suspect, this isn’t an electrophilic aromatic substitution reaction.) In this substitution reactionthe C-Cl bond breaks, … See more Unlike in electrophilic aromatic substitution, there are no “ortho-,para-” or “meta-” directors. The position of substitution is controlled by the placement of the leaving group. … See more One of the most eye-opening aspects of nucleophilic aromatic substitution is noting that fluorine is often used as a leaving group. This is seen in Sanger’s reagent for sequencing peptides, to take one example (more on that below). … See more crosswicks library nj
