Hey hello everyone in this particular question what we can observe that the pentanol is reacting with acetic acid which is giving us pental acetate okay and it is given the question itself those is the given data that means pentanol is reacting with acetic acid which is giving us pental acidate i have written the reaction over here please look into it that means what c s3 c h2 c s2 h is reacting with c s3 c o h in the presence of h plus which is called the acid that is giving us c s3 c s2 c s2 cs2 cs2 o cocs3 right so this is the this is the reaction you can see over here and the question is how it is formed that means mental aceted how did it form that means we have to go through the mechanism part so let us go to the mechanism part so that you can understand how this is formed right and the mechanism part i'm going to write over here the first part is very simple that is the acidic acid part ch3 c double bond o oh will undergo in the presence of h plus and oxygen will react with h plus ion so that cs3 one second yeah so c s3 c double bond o h bond will be formed over here that is oh and on the oxygen atom it will get positive charge and we know that the posturias cannot get a cannot present on the oxygen atom oxygen cannot bear the positive charge on it right so for that reason why what will happen from the downside from the downside alcohol group will attach alcohol group will be attached to the carbon atom so what is going to happen this double burn will shift to this positive charge to make it neutral right to make it neutral so that it will give us product over here now that is c h3 c okay one second yeah yeah i'm going to raise this one very clear i have to write ch3 c, o h atom, here it is o h and here it is oxygen rh.
02:17
On the oxygen atom you will again get the positive charge.
02:21
So now what is going to happen? now the proton transfer is going to happen.
02:25
How? let us see that one, right? so here it will the oh group will come to this position, we'll come to this position, and this hydrogen.
02:35
Hydrogen atom will shift to like this.
02:37
So in this way the corresponding product is now will be formed as what? that is carbon atom is here over here.
02:45
There is oxygen oh.
02:47
Okay, oxygen oh and here this will be like one second yeah this will be o this r group is what? here the r group is methyl group, sorry alkyl group and this alkyl group i have taken over here directly as c5h level.
03:05
Okay c5 h11 so i can write over here that is c5 h11 very simple okay and here it is h group is also present oh sorry oxygen is also sorry sorry sorry okay so now what will happen this o c5 h11 will be formed and here it is what is going to form that is here it is c h3 methyl group is present and here it is o positive hydrogen atom hydrozan is present.
03:39
Why because it due to the proton transfer okay i'm going to write over here this is due to this proton transfer right proton transfer now what will happen now what will happen this whole group okay i'm going to show over here this whole group h2 will be out liberated out after after liberating out or after removing the h2 i uh.....
