  1. 1. diethyl ether is a polar aprotic solvent which if you remmember from orgo 1 is prefered for SN2 reactions.

    2. Diethyl ether is a common solvent in reduction reactions and LAH has the highest solubility in diethyl ether over other etheral solutions.


  2. the diethyl ether acts as the solvent whike the lithium aluminium hydride acts as the reducing agent
