Here we are looking to identify the highest priority groups across some double bonds, where if we have a z configuration, that means we have the highest priority groups on the same side.
00:14
If we have an e configuration, we have the highest priority groups on opposite sides.
00:22
So looking at the first structure, it looks as follows.
00:29
Hydrogen, ch3, ch2oh, ch3.
00:35
So what we need to do is draw mirror line down the centre and then pick out the highest priority groups on each side.
00:50
So, ch3 have a higher relative atomic mass compared to a hydrogen, looking at the periodic table.
00:58
Ch2oh, again, higher priority.
01:02
So therefore, we have z configuration for part a.
01:06
Moving on to part b, we can draw out our structure first.
01:12
Ch2, ch2, ch2, ch3.
01:17
So we've got an alkyl chain, we have a ch2, ch2f.
01:21
What a fluorinated material and ch3, a methyl, and again a hydrogen.
01:26
So imagine that meriplane down the center identify the highest priority groups across both sides of the double bond...
