From its structure, we can see that vanillin does not have a ketone functional group, but it has an aldehyde. It also has a phenol and ether functional group. For that reason, I wouldn't categorize is as just an aldehyde.
alcohol
In this molecule you have 2 different carbon chains separated by the functional ether group. The generic formula for an ether is R-O-R. Your first group is a 2 carbon chain called an ethyl and your second group is a 1 carbon called a methyl. So you have a methyl group and ethyl group which must be put together in in alphabetical order ethyl-methyl and then followed by the functional group -ether. Thus your final molecule name is ethyl-methyl-ether. Good luck with the rest of O. Chem!
