If primary alcohol is oxidized once, you get an aldehyde group (if oxidized twice you would get a carboxylic acid)
If secondary alcohol is oxidized, you get a ketone:
If both oxidize, you have a ketone with an aldehyde substituent:
I'm not up on the newest organic nomenclature but I would use these names. I have found that there is no ABSOLUTELY correct way; i.e., many names are correct. I would advise getting a second opinion.
2-ethyl-1-hydroxy-3-hexanone (or hexan-3-one).
1-hexanal is redundant. In an aldehyde, the aldehyde carbon is always #1.
After seeing DrBob's answer, I'd change the substituent orders in my answer to be alphabetic:
I know you're right about the 1 being redundant; however, I stick it in anyway. It isn't absolutely correct but it isn't absolutely incorrect either (at least in my mind). :-).
