Sabatier Senderns reaction involve _____________ in presence of Ni?
Correct answer: A. Aalkene & H2
- A. Aalkene & H2
- B. alkene & O2
- C. alkene & N2
- D. alkyne & Cl2
Explanation
The Sabatier-Senderens reaction hydrogenates an alkene by adding H2 across its carbon-carbon double bond in the presence of nickel, producing an alkane. A student may choose alkene and O2 because both are gases involved in industrial reactions, but oxygen causes oxidation rather than hydrogenation.

About Alkenes
Alkenes are unsaturated hydrocarbons containing a carbon-carbon double bond with sigma and pi components and restricted rotation. Their reactions include electrophilic addition of hydrogen, halogens, hydrogen halides and water, with Markovnikov orientation, oxidation, combustion and polymerisation, while their preparation commonly involves elimination from alkyl halides or alcohols.
