- m-Dinitrobenzene (1,3-dinitrobenzene): a benzene ring (C6H4) with two -NO2 (nitro) groups in a meta relationship, i.e. at ring positions 1 and 3 (separated by one unsubstituted carbon). Structural formula: a benzene ring with -NO2 at C1 and -NO2 at C3, and H at C2, C4, C5, C6.
- p-Dichlorobenzene (1,4-dichlorobenzene): a benzene ring (C6H4) with two -Cl groups in a para relationship, i.e. directly opposite each other at ring positions 1 and 4. Structural formula: a benzene ring with -Cl at C1 and -Cl at C4, and H at C2, C3, C5, C6. …
