Name the following:

Question

CH3CH2CH(OH)COOH
CH3OCH2CH2CH3
C4H9O(C=O)CH3

Answer 1

How closely do you need to follow IUPAC guidelines?
I would name the last one as
n-butylacetate but the guidelines probably say n-butylethanoate.
The middle one is an ether.
n-methylpropyl ether.
The first one is an acid with a hydroxy group on the alpha carbon atom.
