Step by step solution

01

Organic reactions

Organic reactions involve the reagents like Grignard reagent (R-Mg-X) and organolithium reagents (R-Li). This reaction occurs in a solvent like dry ether, THF, and hexane.

02

Products of the reactions (a) and (b)

a. When bromoethane reacts with Mg in the presence of dry ether, it results in the formation of Grignard reagent (R-Mg-X).
