Final answer:
The conjugate base of the acid CH3CH2CH2OH (propanol) is CH3CH2CH2O- (propanolate), which is formed by removing a proton from the hydroxyl group.
Step-by-step explanation:
The conjugate base of an acid is formed by removing a proton (H+) from the acid. The given acid is CH3CH2CH2OH (propanol).
To find its conjugate base, we remove one hydrogen from the hydroxyl group (-OH) to form CH3CH2CH2O-. This anion is the result of the propanol molecule losing a proton and becoming propanolate, the conjugate base.
