Hi everyone.
00:01
As per the question we have to sketch the scheme for sodium borohydra reduction to pencil and its mechanism.
00:08
First of all, let us draw its scheme.
00:11
That is, benzide that can be drawn as follows, having both ph at the tail end and carbonyl group in the middle.
00:23
This is pencil.
00:26
This reacts with sodium borohydride, n -a -p -h4.
00:32
Will keep mesohidrobenzyme that having the structure like this th, th, h, oh it's, this is mesohydrofenzoil.
00:54
Now let us write its mechanism.
01:00
Just for what happens, we can draw the structure for pencil ph double bond of double bond of ph.
01:12
It is reacting with borohydrate, that is boron with poor hydrogen.
01:22
What happens? this hydrogen will attach the carbonyl group here and this double bond breaks and goes with boron.
01:33
We will get a structure like this.
01:35
Here we can write ph.
01:40
Here the double bond of ph...
