A) hydrogenolysis
B) hydrogenation
C) decarboxylation
D) hydration
Correct Answer: B
Solution :
Oils can be converted into solid fats by the process of hydrogenation. Hydrogenation: The vegetable oils containing glycerides of unsaturated fatty acids, undergo catalytic hydrogenation with hydrogen in presence of finely divided nickel. This results in conversion of a liquid glyceride (ie, an oil) into solid glyceride (ie, a fat) \[\underset{olein\,(an\,oil)}{\mathop{\underset{\begin{smallmatrix} | \\ C{{H}_{2}}OCO{{C}_{17}}{{H}_{33}} \end{smallmatrix}}{\overset{\begin{smallmatrix} C{{H}_{2}}OCO{{C}_{17}}{{H}_{33}} \\ | \end{smallmatrix}}{\mathop{CHOCO{{C}_{17}}{{H}_{33}}}}}\,}}\,+3{{H}_{2}}\xrightarrow[{}]{Ni}\]\[\underset{stearin(a\,fat)}{\mathop{\underset{\begin{smallmatrix} | \\ C{{H}_{2}}OCO{{C}_{17}}{{H}_{35}} \end{smallmatrix}}{\overset{\begin{smallmatrix} C{{H}_{2}}OCO{{C}_{17}}{{H}_{35}} \\ | \end{smallmatrix}}{\mathop{CHOCO{{C}_{17}}{{H}_{35}}}}}\,}}\,\]
