Vedclass · Answer

(B) The given reaction is the alkaline hydrolysis of a triglyceride (fat or oil),which is known as saponification.The reaction is:$CH_2(OCOR_1)-CH(OCOR_2)-CH_2(OCOR_3) + 3NaOH 	o CH_2(OH)-CH(OH)-CH_2(OH) + 3R-COONa$Here,the product $(A)$ is $CH_2(OH)-CH(OH)-CH_2(OH)$,which is commonly known as glycerol (or propane-$1,2,3$-triol).Therefore,the correct option is $(B)$.
