Does anyone know what CH3CH2CH(OH)COOH or C4H9O(C=O)CH3 is?

Answer 1

I believe the firt one is 3-hydroxybutanoic acid.
I believe the second one is
butyl acetate.

Answer 2

alpha -hydroxylbutyric acid (CH3CH2CH(OH)COOH) is this correct?

Answer 3

Yes, that's one way of naming it. My name SHOULD have been 2-hydroxybutanoic acid (I stated counting from the wrong end--a common error). The IUPAC name is butanoic acid for the parent compound but the older name of butyric acid abounds.

Answer 4

Yes, I agree with 2-hydroxybutanoic acid.

Answer 5

the ecquisition?
