A) Hydrolysis
B) Saponification
C) Neutralisation
D) Acidification
Correct Answer: B
Solution :
Saponification: \[\begin{matrix} \underset{|}{\mathop{C}}\,{{H}_{2}}OCO{{C}_{17}}{{H}_{35}} \\ \underset{|}{\mathop{C}}\,HOCO{{C}_{17}}{{H}_{35}} \\ \underset{stearin\,\,(fat)}{\mathop{C{{H}_{2}}OCO{{C}_{17}}{{H}_{35}}}}\, \\ \end{matrix}+3NaOH\xrightarrow{{}}\begin{matrix} \underset{|}{\mathop{C}}\,{{H}_{2}}OH \\ \underset{|}{\mathop{C}}\,HOH \\ \underset{glycerol}{\mathop{C{{H}_{2}}OH}}\, \\ \end{matrix}\] \[\underset{\underset{(soap)}{\mathop{sodium\,\,stearate}}\,}{\mathop{+3{{C}_{17}}{{H}_{35}}COONa}}\,\]
