Okay, so we have to explain the difference between a substitution reaction and addition.
00:05
So in a substitution reaction, we are just swapping one group out for another.
00:11
And the one group we're starting with is an aquilite because they're going to leave in groups.
00:16
So this could be either bromine or chlorine.
00:19
It's not going to be fluorine because they're less reactive than the other aquilates.
00:31
So if we had a secondary aquilite, and we would react this with a, um, a, um, a, polar preric solvent we're going to have an s in 1 slash e1 reaction so the s for substitution the n is nucleophilic and the polar purdic solvent is going to be could be methanol or water and as a result we're going to get we're going to add a methoxy group and get hbr as a side product because the bromine is going to deprotinate methanol and we could also get the e1 product as well which would be an alkyne.
01:27
But for an addition reaction, we're really just adding a group to either an alkyne or an alkyne.
01:39
So if you react to butene or one butene with hbr, the alkyne is going to be a nucleophile.
01:49
It's going to depredate the acid, and it's going to add the hydrogen to the less substitute to carbon so we can get a more stable carboketone...
