Benzoyl

In organic chemistry, benzoyl is the acyl of benzoic acid, with structure C₆H₅CO-. It should not be confused with benzyl, which is the radical or ion formed from the removal of one of the methyl hydrogens of toluene (methylbenzene). Whereas a benzyl substituent is commonly abbreviated "Bn", a benzoyl group is in contrast given the symbol "Bz".
