The fluorotoluenes (more precisely monofluorotoluenes) form a group of substances in chemistry that is derived from both toluene and fluorobenzene . The structure consists of a benzene ring with an attached methyl group  (–CH ₃ ) and fluorine  (–F) as substituents . Their different arrangement results in three constitutional isomers with the empirical formula C ₇ H ₇ F.

properties

The 4-fluorotoluene, which has the highest symmetry, has the highest melting point. The introduction of the fluorine atom changes the boiling point only slightly compared to toluene (111 ° C).
