Hello.
00:02
In this question, we are asked to write the reagents and the reactions for the following conversions.
00:09
So let's start with the first run where we are starting with ethylene.
00:14
So we need to finally form two mutine.
00:21
So that is a final product.
00:22
So in order to do that, first we will use n .a.
00:25
N.
00:25
H2 and h3.
00:28
And that will form the following.
00:30
So we have ch triple bond, c minus, and na plus.
00:35
And now if we treat this with an alkyl halide, like ch3i, because that is somewhat of what we need the product to be, this is what we obtain.
00:45
Now let's again treat this with n .a.
00:48
N .h2 and h3.
00:50
Now here we will get n .a.
00:53
Plus c minus.
00:55
So the hydrogen is being replaced.
00:57
And again let's add ch3i.
01:01
So finally we get ch3ch sorry, ch3c, triple bond c, c, ch3.
01:11
And now we need to eliminate this triple bond.
01:14
So for that we can use n -a and h3...
