- m-Dinitrobenzene: benzene (C6H6) with two nitro (-NO2) groups in the meta relationship, i.e. at ring positions 1 and 3. Structure: C6H4(NO2)2, with NO2 on carbon-1 and carbon-3 of the six-membered ring, and H on the remaining four ring carbons.
- p-Dichlorobenzene: benzene with two chlorine atoms in the para relationship, i.e. directly opposite each other at ring positions 1 and 4. Structure: C6H4Cl2, with Cl on carbon-1 and carbon-4, and H on the remaining four ring carbons.
- 1,3,5-Trimethylbenzene (common name mesitylene): benzene with three methyl (-CH3) groups placed symmetrically at alternating ring positions 1, 3, and 5. Structure: C6H3(CH3)3, with CH3 on carbons 1, 3, and 5, and H on carbons 2, 4, and 6. …
