A mixture of 2-bromopropane and bromoethane is heated with sodium metal in ether medium. The alkane/s formed during the reaction is/are
View answer and explanation
Correct option: D
All of these
Option D (All of these) is correct because the reaction involves a Wurtz reaction, where alkyl halides react with sodium metal in dry ether to form alkanes. 2-bromopropane forms 2,3-dimethylbutane, bromoethane forms butane, and a cross-coupling reaction forms pentane.
