In chemistry, the nitrobenzyl chlorides form a group of substances that are derived from both benzyl chloride and nitrobenzene . The structure consists of a benzene ring with attached chloromethyl (-CH 2 Cl) and nitro group (-NO 2 ) as substituents . Their different arrangement ( ortho , meta or para ) results in three constitutional isomers with the empirical formula C 7 H 6 NO 2 Cl.
properties
The nitrobenzyl chlorides are solids. The 4-nitrobenzyl chloride, which has the highest symmetry, has the highest melting point.
