Benzene
A naturally occuring aromatic compound, which is a very stable planar ring strucure with delocalised electrons
1 of 15
Kekule's Benznene Model
A six-membered ring with alternating single and double bonds between carbon atoms
2 of 15
Substitution reaction
A group/atom is exchanged for another group/atom in aq chemical reaction
3 of 15
Benzene derivative
A benzene ring that has undegone a substitution reaction
4 of 15
Electrophilic substitution
A substitution reaction where an electrophile is attracted to an electron-rich atom or part of a moleucle and a new covalent bond is formed from the electrophile accepting an electron pair
5 of 15
Reaction mechanism
A model with steps to expalin and predict a chemical reaction
6 of 15
Nitration of benzene
An electrophilic substitution reaction where a hydrogen atom is exhchanged for a nitro group (NO2)
7 of 15
A Friedel-Crafts reaction
A substitution reaction where hydrogen is excahnged for an alkyl/acyl chain
8 of 15
Acyl chloride
A functional group RCOCl, and is very reactive
9 of 15
Phenols
An aromatic compound where a hydroxyl group is directly attached to the aromatic ring
10 of 15
Directing effect
A functional group attached directly to an aromatic ring affects which carbon atoms are more likely to undergo substitution
11 of 15
Bromination of phenols
Triple substitution to form a white precipitate of 2,4,6-tribromophenol
12 of 15
Nitration of phenols
Dilute nitric acid --> mixture of 2 and 4 nitrophenol. Conc. nitric acid --> 2,4,6-trinitrophenol
13 of 15
Nucleophile
A species attracted to an electron-deficient part of a molecule, where it donates a pair of electrons to make a new covalent bond
14 of 15
Hydrolysis
A chemical reaction where water causes the breaking of bonds, in a decomposition reaction
