Okay, this problem is asking us to predict the reaction that is going to occur from these two reactants.
00:05
Okay, so i have my alkyn, and i have my deprotinated nh3, otherwise known as nh2.
00:12
Okay, so hypothetically, i'm just going to get an acid -based reaction in which i have to proteinate my nh2 with the acidic proton on my alkyne.
00:20
Okay, so it's basically going to occur like this, in which i take off that proton and move the electrons onto that side of the alkyn.
00:26
Okay, so this is going to be my hypothetical product.
00:30
In which i have my deprotonated alkyne like this, with my set of lumbase on that terminal side, and then my protonated nh2, otherwise known as nh3.
00:39
Okay, so now, in order to determine whether that would actually occur, we definitely have to look at the pkks.
00:45
Okay, so in terms of pkk in reactions, we always have to go from more acidic into less acidic.
00:53
So we're going from a strong acid slash strong base into a weaker acid and weaker base.
00:58
Okay.
01:00
Here i have a relatively strong acid of my alkyne which has a pk a approximately 25.
01:09
And h2 we can't really assign a reliable pkk with that because it's already in the basic form.
01:14
So there probably is a pkk associated with it but it would be very very, very high...
