Hi, in this problem we are given the names of some organic compounds.
00:06
We have to draw the structure of these compounds.
00:09
Also, we have to determine the compounds which are optically active.
00:14
So first, we will draw the structures of all these compounds.
00:17
The first one is one, three dichloropentine.
00:20
This compound has five carbon atoms with two chlorine present at carbon one and three.
00:29
So we can write the structure as ch2 having cl that is chlorine bonded to it ch2 ch2 chcl ch3 where this carbon is 1, 2, 3 carbon number 1 and 3 has chlorine bonded to them the next one is 3 -cluro 2 -5 tromethyl hexene.
01:08
Here we have 6 -carbon atom chain with chlorinate carbon 3 and methyl group at carbon 2 and 5.
01:17
We have ch3, c having 2 methyl groups, then third carbon having chlorine bonded to it, ch2, ch having methyl group, bonded to it, ch2, ch2, h2, 3.
01:41
We can write the number of carbon atoms as shown here.
01:50
Then we have the next compound named as 1 -romo 1 chlorobutene...
