Vedclass · Answer

(D) The reaction involves the heating of lactic acid $(CH_3-CH(OH)-COOH)$.When alpha-hydroxy acids like lactic acid are heated,they undergo intermolecular esterification to form a cyclic dimer known as a lactide.Two molecules of lactic acid lose two molecules of water to form the cyclic diester,$3$,$6$-dimethyl$-1,4-$dioxane$-2,5-$dione.Therefore,the product $[Y]$ is the lactide.

In the reaction sequence:
$CH_3-CH(OH)-COOH$ $\xrightarrow{\Delta } [Y]$
$[Y]$ will be:
