Okay, we are starting with acetylene, and our first reaction is with sodium amid, which we know would deprotonate our acetylene and give us an acetylite ion, which in the second portion of this first reaction, basically we are reacting then with a bromo alkan.
00:24
So we expect then a sn2 reaction kicking off the bromine giving us now are no longer settling our alkyne right with now this sort of cyclobutane attached.
00:57
Okay again we're going to react it with sodium amid which will now deprotonate the other side of the alkyne to give us again an alkyne.
01:07
Ion.
01:23
Okay.
01:24
And then in the fourth step, we're reacting this with this sort of tertbutyl, uh, turt pentyl bromide, which again, sn2 reaction kicks off the bromine.
01:53
And we get our final product like so.
02:09
Okay.
02:09
Now which of these does this match? uh, some of them are missing carbons.
02:15
I think that's the main issue, uh, but four.
02:17
Is precisely what that matches...
