The electrophilic substitution reaction between benzene and ethanoyl chloride What is acylation? An acyl group is an alkyl group attached to a carbon-oxygen double bond. If R represents any alkyl group, then an acyl group has the formula RCO-.he facts The most reactive substance containing an acyl group is an acyl chloride (also known as an acid chloride). These have the general formula RCOCl. Benzene is treated with a mixture of ethanoyl chloride, CH3COCl, and aluminium chloride as the catalyst. A ketone called phenylethanone is formed.
All you have to remember most importantly, is that Ionic is metal + non-metal For examples, in KCl, Potassium is an alkali metal and Chloride is a hallide (non-metal) In SiCl4, Silicon and Chlorine are both non-metals so form a covalent bond (and atoms that form this bond are termed molecules).ut there are also complex ions such as NH4+ and SO42- which form ionic bonds despite containing non metals. So best way is to remember the valency or charge of each simple or complex ion. A compound consisting of a cation(+ ve charge) and an anion(-ve charge) will be instantly recognized as ionic.
