Hydrogenation of fatty acid is ?: (A) Hydrolysis by Alkali, (B) Auto-oxidation of PUFA, (C) Addition of hydrogen to unsaturated fatty acid, (D) Addition of hydrogen to saturated fatty acid
Answer is C. Ans. is 'c' i.e., Addition of hydrogen to unsaturated fatty acidAddition of hydrogen atoms to unsaturated fatty acid refers to hydrogenation.
