Aromatic Compounds ( Test 3 )

Aromatic Compounds

• benzene- C6H6
• Aromatic compound- something with benzene, flat ring structure, represented by 2 structures (donut) pi electrons are shared equally among 6 carbon atoms, have a stable aromatic bonding system, are resistant to many reactions, undergo substitution reactions
• A benzene with a single substituent is often named branch+benzene
• Methylbenzene- toluene, aromatic alcohol- hydroxybenzene- Phenol
• benzene ring with two or more substituents is numbered to give the lowest numbers to the side groups, common names use prefixes (ortho- 1,2) (meta-1,3) (para-1,4) (ex= o-dibromobenzene)
