So phenol, when it reacts with the acetic acid, with the acetic acid, it can undergo the osilation or the cicillation.
00:34
In both the cases there will be the release of water.
00:40
And what will be the product? the product will be an ester so what will be the product will be an ester so what will be the product here it will be placed at other sides and these two products can what happens to the product this product is a bit unstable and it undergoes fries rearrangement re -arrangement arrangement to convert into the product b.
01:41
Now the reagent is r, co, cl and ch3 cooh for oscillation.
02:01
Now another thing which is required for oscillation is anhydrous alcl3, that is the aluminum chloride.
02:19
Now, phenol, if we're talking about the phenol, so phenol is an orthopara directing group.
02:28
So, in the group rcocl, acts as an electrophile.
02:32
So, if it is acting as an electrophile, it will attack first.
02:37
So in the mechanism, the phenol, which is an orthopara directing group, is attacked by an electrophile which is having the axis of okay so this electrophile will attack here and this lone pair of oxygen will be shifted okay so this reaction occurs in the presence of anhydrous alcl3 and the product formed is this.
03:22
Now for example if you are taking the ch3 co cl in the presence of aluminium chloride then the cs3 co plus is formed and alcl4 minus is formed.
03:47
This asyle group assile group.
03:52
So we got this asile group from the acetyl chloride.
03:57
This is the estile chloride.
04:04
And this acyl group is the electrophile.
04:09
Electrofile because it is electron deficient.
04:12
So it will be electrophile.
04:14
Now the resonance will occur in the structure that is formed as a product.
04:19
That means this is structure.
04:21
Okay.
04:21
This is structure...
