Hi dan,
a mistake on my part in regards to the carbonyls.
Guys could you give me an indication if I am using a correct method.
This is an example from my notes.
It gives H as lowest priority.
"When we look at the atoms attached to the Carbons we can see
1. 3*Hydrogen atoms (methyl chain)
2. 2*hydrogen atoms and 1 oxygen atom (OH chain)
3. 3*oxygen atoms" (COOH chain)
so it gives the acid group priority, followed by the alcohol and then the methyl.
Now I thought you looked at what was directly attached to each carbon.
I agree with the methyl carbon - attached to HHH
and the OH carbon attched to HHO
but the next carbon, has 2 hydrogens and another carbon attached, but in the notes they have quoted the atoms attached to the carbonyl carbon. Is this correct, as if I had of done it my way, I would have given priority to the alcohol, then acid chain, then methyl...I am very confused now.
