In chemistry, fluorobenzyl alcohols form a group of substances that are derived from both benzyl alcohol and fluorobenzene . The structure consists of a benzene ring with an attached hydroxymethyl group (–CH 2 OH) and fluorine (–F) as substituents . Their different arrangements ( ortho , meta or para ) result in three constitutional isomers with the empirical formula C 7 H 7 FO.
properties
The introduction of the fluorine atom changes the boiling point only slightly compared to benzyl alcohol (206 ° C).
