Alkylation & Acylation of benzene

Question 1

What is alkylation of benzene?

Answer 1

When H atom in benzene ring is substituted with an alkyl group
Requires electrophilic substitution and use of halogen carrier, AlCl3

Question 2

What is acylation of benzene?

Answer 2

The susbstitution of H atom in benzene ring with an acyl group
eg. ethanoyl (Ch3CO), propanoyl (CH3CH2CO)
Requires electrophilic substitution and use of halogen-carrier AlCl3

Question 3

Why are acylation and alkylation important in organic synthesis?

Answer 3

They increase the number of carbon atoms in the structure

Question 4

How does alkylation of benzene work?

Answer 4

React benzene with a haloalkane in presence of AlCl3 catalyst. Also produces HCl.

Question 5

How does acylation of benzene work?

Answer 5

React benzene with an acyl chloride in presence of AlCl3 catalyst. Also produces HCl.

Question 6

What is the suffix of an acyl?

Answer 6

-oyl

Question 7

What is the suffix of an alkyl?

Answer 7

-yl
