Okay, this problem is asking us to draw the curved arrows to represent the mechanism of this reaction.
00:05
So let's go ahead and go to this first one.
00:07
Okay, so on this first one, we see that we have this alcohol on the left, and we're going to react it with hcl, in order to produce these two compounds over here, the protonated alcohol, as well as the chloride ion.
00:17
So, in order to undergo this reaction, i have to do a couple of arrows.
00:20
I have to show the movement of electrons from this oxygen, and i'm going to move those electrons onto this hydrogen.
00:28
Okay, so the reason i'm doing this is because hcl is a very strong acid versus my alcohol.
00:34
That is a very, not a particularly strong base or particularly basic, but it is basic enough to get protonated by my very acidic compound, which is hcl.
00:43
So that relatively, it's actually considered to be a weak base, but that base is going to get protonated by my hcl.
00:50
It's going to take off that proton, and after i take off that proton, i'm going to have to move the electrons from that hcl bond onto the chlorine.
00:57
Okay, so that is going to produce the protonated alcohol as well as the chloride ion.
01:02
So that chlorine is going to have that extra set of electrons, meaning that it has that negative charge...
