0:00 Hello students.

00:01 So, in this video we are going to talk about isomers.

00:05 So, isomers are compounds having same molecular formula but different structural formula.

00:28 So, let us take a look at an example.

00:32 So, the first example we have is c3h7cl.

00:37 So, firstly we will simply draw a straight chain compound and we will add cl in the terminal and the rest will fill it with hydrogen.

00:49 So, you can see here the carbon is 3 and hydrogen is 7, 3 plus 2 plus 2 and chlorine is 1.

00:56 So, this is one isomer.

00:57 Then we can put this chlorine in the middle carbon.

01:02 So, if we will do that we have to put one h here.

01:06 So, this is also c3h7cl.

01:10 So, these are these two are isomers of c3h7cl.

01:15 Now, let us look at second compound.

01:19 So, in the second compound i have c2h4o.

01:23 So, single o is present in alcohols, aldehydes or cyclic maybe compounds.

01:34 So, we can from c2h4, we can write c2h4 as h2c like an alkene.

01:43 So, double bond c.

01:46 Now, we will attach oh here and we will add h here.

01:49 So, we are getting c2h4o.

01:51 Next, we can make it in an aldehyde...
