Vedclass · Answer

(B) The structure of ethyl $3$-oxobutanoate is $CH_3-CO-CH_2-COOC_2H_5$. This compound exists in equilibrium with its enol form,ethyl $3$-hydroxybut-$2$-enoate,which has the structure $CH_3-C(OH)=CH-COOC_2H_5$. This type of isomerism,where a compound exists in two readily interconvertible forms differing in the position of a proton and a double bond,is known as tautomerism. Therefore,these two compounds are tautomers.

Ethyl $3$-oxobutanoate and ethyl $3$-hydroxybut-$2$-enoate are ................... of each other.
