Vedclass · Answer

(A) The iodoform test is given by compounds containing the $CH_3CO-$ group or compounds that can be oxidized to this group. Upon hydrolysis and subsequent heating (decarboxylation),$\beta$-keto esters yield ketones. Specifically,$1$-acetylcyclobutane$-1-$carboxylic acid ethyl ester undergoes hydrolysis to form a $\beta$-keto acid,which upon heating loses $CO_2$ to form acetylcyclobutane (a methyl ketone). This methyl ketone $(CH_3-CO-R)$ gives a positive iodoform test with $I_2/NaOH$ to form $CHI_3$ (iodoform) and a carboxylate salt.

Which of the following compounds,upon hydrolysis followed by heating,gives a product that yields a positive iodoform test?
