Are substances with an HO- Alcohols? What about items that are O-C with a O double bonded to the C and above it? Are they acids? Thanks!

In inorganic chemistry, compounds with OH generally are bases (NaOH, KOH, Al(OH)3, etc). In organic chemistry, an OH attached to a C is an alcohol. -COOH is an acid. C-O-C is an ether.

RCOOH = acids
ROR ethers
RCOOR = esters
RNH2 amines
RCONH2 amides.
