What is another word for electrophilic substitution?
Pronunciation: [ɪlˌɛktɹə͡ʊfˈɪlɪk sˌʌbstɪtjˈuːʃən] (IPA) 
Electrophilic substitution is a chemical reaction in which an electrophile (an atom or molecule that seeks electrons) replaces an atom or group of atoms in a molecule. This term is often used in organic chemistry, where electrophilic substitutions occur frequently. Synonyms for electrophilic substitution include electrophilic attack, electrophilic addition, and electrophilic substitution reaction. These all refer to the same basic process of an electrophile reacting with a molecule to replace an atom or group of atoms. In some cases, the term electrophilic aromatic substitution may also be used to describe this process, specifically for reactions involving aromatic compounds. Regardless of the terminology, electrophilic substitution reactions are a key element in many chemical processes.
