Question

What is the IUPAC name of acetylation product of \[anisole\]?

Answer 1

Hint: First step to solve the answer is to find the acetylation product of \[anisole\]. Then following the IUPAC rule name the product formed by this process. In acetylation an acetyl group is added to the aromatic ring.

Complete Answer:
The process where an acetyl group is added to a compound because of its replacement with that of an active \[hydrogen\] atom is called acetylation. An acetyl group is included in the organic compound, such a compound is termed as acetates or acetate esters. Acetyl group consists of carbonyl atoms or a \[carbon\] atom bonded in double pairs with \[oxygen\] or a methyl group on end.
Now that we know the acetylation process, we can determine the product.
When \[anisole\]reacts with acetyl chloride it yields a ketone product. This reaction takes place in the presence of a catalyst \[aluminium{\text{ }}chloride\], it first generates an electrophile which gets attached to a benzene ring to give a major product \[4 - methoxyacetophenone\]
In the reaction only major product is shown which is an ortho product. The alkoxy group is always an ortho-para directing in electrophilic aromatic substitution reactions.

The major product name is \[4 - methoxyacetophenone\] or \[1 - (4 - methoxyphenyl)ethanone\]. Here the functional group is ketone, therefore the suffix \[ - one\]. It is also known as Acetanisole which smells like butter or caramel and has a sweet and fruity smell.

Note:
There are many other examples of acetylation. One of them is acetylation of glucose where bond formation takes place between the extra electrons of nucleophilic \[oxygen\] with the acetyl group, which results in substitution of \[hydrogen\] atoms from phenol group.
