The reaction 2RX + 2Na -> RR + 2NaX is an example of:
Correct answer: D. Wurtz reaction
- A. Cannizaro's reaction
- B. Kolbe's reaction
- C. Sabatier & Senderen's reaction
- D. Wurtz reaction
Explanation
Option D is correct as the Wurtz reaction is an organic chemical coupling reaction wherein sodium metal is reacted with two alkyl halides in the environment provided by a solution of dry ether to form a higher alkane along with a compound containing sodium and the halogen. The general form of the Wurtz reaction equation can be written as follows: 2R-X + 2Na → R-R + 2Na+ X- It can be observed from this equation that the two R groups are joined, yielding an alkane with a longer chain along with NaX, where X is a Halogen.

About Alkanes
Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
