1. What type of mechanism is involved in a Friedel-Crafts alkylation reaction?
2. What type of reagent is AlCl3 in a Friedel-Crafts alkylation reaction?
3. Which of the following molecules will fail to undergo a Friedel-Crafts alkylation reaction?
4. During a Friedel-Crafts alkylation reaction the halogen atom present on the halogenalkane donates a lone pair of electrons to the Lewis acid and is therefore acting as a base.
5. Which of the following groups will activate a benzene ring towards further electrophilic substitution?
6. A Lewis acid is an electron pair while a Lewis base is an electron pair .
7. Which type of carbocation is the most stable when formed during a Friedel-Crafts alkylation reaction?
8. One reason why aryl halides do not undergo a Friedel-Crafts alkylation reaction is that the C-X bond is too .
9. What happens to the delocalised pi electron system in a benzene ring during electrophilic substitution reactions?
10. What intermediate is formed during the reaction between 2-chloropropane and AlCl3?
11. Which of the following is not a common Lewis acid used in a Friedel-Crafts alkylation reaction?
12. One of the major limitations of Friedel-Crafts alkylation reactions is that they often under reactions, this is where alkyl groups are added onto an aromatic ring.
13. Which of the following species is likely to remove a proton (H+) in a Friedel-Crafts alkylation reaction?
14. Which of the following can act as a Lewis base in a Friedel-Crafts alkylation reaction?
