In this video, we are going to look at some addition reactions within organic chemistry. So what is an addition reaction? Well, firstly, it occurs with only unsaturated hydrocarbons. If you’re, not sure about what the word unsaturated means, it simply means compounds that have either a double or triple bond.

So these addition reactions are going to occur where we have these multi bonds, where we have these double and triple bonds occurring, and here’s, this a general picture, so we ‘ Ve got a compound that has this one has a double bond.

We’re, going to be adding it together with compound X Y and you’ll notice that the double bond is gone. You know with a single bond and X is on one side Y is on the other. So let’s. Take a look at an example here so right in addition, reaction for ethene and bromine gas, so there is ethene and there is bromine gas.

So what’s going to happen in this reaction? Is our double bond is going to be gone. We’re gonna end up with a single bond, and we’re. Then gonna end up with one bromine on either side. Now, in terms of naming these, we started with ethene, we can buy that with bromine gas.

Now, what we got here is we’ve got. This is a first carbon. This is our second carbon or vice Ferger set it’ll work either way we have bro means on both of those. So we’re gonna call this a one two die bromo ethane remember this is now an ethane.

It’s when I got single bonds example to write a an equation to represent the addition reaction between propane, so that has three carbons in a double bond and hydrobromic acid. All right. So here’s, essentially what we’re gonna be doing so.

What’s gonna happen is there are actually two different outcomes because we could put the hydrogen on that carbon and the bromine on that carbon, meaning we’d, have the bromine in the second spot, or you could flip it around.

You could have the bromine in the first spot, so there are actually two acceptable outcomes for this reaction and there they are so again in this one. Here we’ve got the hydrogen and the bromine on the second carbon, and for this one we’ve, just flipped them around, and now we have the bromine on the first carbon
