Q.
Which of the following reactions is used for producing symmetrical alkane with double carbon atoms?
J & K CETJ & K CET 2019Hydrocarbons
Solution:
In Wurtz reaction, alkyl halides react with metallic sodium in presence o f dry ether to form symmetrical alkanes containing double the number o f carbon atoms present in the alkyl halide
$R —X +2Na+X—R \xrightarrow{\text{Dry ether}} R—R+2NaX$
