Compound with two functional group Compound X has 3 carbon atoms in one molecule. It contains a primary alcohol and a carboxylic acid functional group.

Draw the displayed formula of Compound X. 

Help! Condensed formula is fine for me!
Draw a chain of three carbon atoms.
Make one of them $\ce{COOH}$. You have two carbon atoms to choose from.
Attach $\ce{OH}$ to one of the remaining carbon atoms to make it a primary alcohol. You have one carbon atom to choose from.
