When 2-bromopropane (also known as isopropyl bromide) reacts with sodium ethoxide (C2H5ONa), it undergoes elimination reactions to form alkenes, not alkanes like propane.
The major product of the reaction between 2-bromopropane and sodium ethoxide is propene (also known as propylene). This reaction is known as an E2 elimination reaction, where the bromine atom is eliminated, and a double bond is formed between the carbon atoms.
The formation of ethyl isopropyl ether is not the major product of the reaction between 2-bromopropane and sodium ethoxide. This reaction typically leads to the formation of propene as the major product through elimination.
This option is not accurate. The major product of the reaction is propene (propylene) through an elimination reaction.
The correct major product when 2-bromopropane reacts with sodium ethoxide is B. Propene (propylene).
