00:01
Okay, so we're going to write the formula for the alcohols that created these products.
00:05
And the first product is a 1 -2 -3 -4 carbon aldehyde.
00:10
We're going to write the adohydde first.
00:20
And if we oxidize a primary, there should be a methyl on carbon 3.
00:28
So if we oxidize a primary alcohol with a weak oxidizing agent like despartumperidene or pcc, we'll get an aldohyd.
00:36
So therefore, we must have had a primary alcohol here.
00:39
To get an aldahide and therefore the structure looks like this it's going to be butanol or three methyl butanol next one is a five carbon ketone keytune ketune is on carbon three and we can only get a ketone from a secondary alcohol so therefore it's going to be three petanol next one is a four carbon carbosoc acid with a methyl and carbon too by the way, this arrow is a retro synthetic arrow.
01:45
It's going backward.
01:47
So this is the products, and this is what we started with.
01:54
Okay, so if we treat a primary alcohol with a strong oxidizing agent, we'll get a carbosyl acid.
01:59
So therefore, this must have started from a primary alcohol, and it was treated with either potassium permogonate, sodium dichromate, or some other strong oxidizing agent.
02:14
But because we have five carbons as well, or, 4 carbons, methyl right here...
