Dear students, some names of some organic compounds are given and they are incorrect by ipcc rules.
00:08
So, you have to draw the structures and give their correct ipac names.
00:12
2 methyl 4 hexine.
00:15
So 2 methyl 4 hexine, 1, 2, 3, 4 hexine, 1, 2, 3, 4, 6, 1, 3, 4, 6, 2, 4 hexine.
00:28
1, 2, 3, 4, hexine.
00:32
Cs3, ch, ch, ch 2, this is ch, ch, ch, ch, ch.
00:39
Now this is the first compound.
00:43
Here numbering, as for the question done from this side, left to right, but this is wrong, because double bond gets this side 4 number, but here from this side to number 2, so numbering must be from right to left.
00:59
1, 2, 3, 4, 5, 6.
01:02
So it is 5 methyl to hexine.
01:10
Now coming to the next one, here 1 3 dimethyl, 1 hexine.
01:16
1, 2, 3, 4, 5, 6.
01:20
So it is 1 hexine, 1 3 dimethyl means here 1 methyl group, then 3.
01:28
So, 1 -3 dimethyl.
01:32
Then here, ch2, ch2, ch3.
01:40
So it is not 1 -3 -3 -3 -dymethyl 1 -hexine.
01:44
This is wrong.
01:44
Numbering must be done from this carbon...
