Let's determine whether the following are cis or trans isomers.
00:06
For a, we'll have bl and br.
00:20
This is in the down position, and this is also in the down position.
00:28
Therefore, this is a cis configuration.
00:33
For b, we've got br here, and here.
00:51
This is in the up.
00:53
And this is also in the up, this is a cis isomer.
01:01
C, you have a methyl group here, and we've got a br group here.
01:15
This is, the bromal group is in the down position, the methyl group is also in the down position, and this is a cisisomer.
01:27
For d, we've got a bromo group here, and a methyl group here...
