What type of reaction occurs when 1-bromopropane reacts with sodium ethoxide? (2023)

Step 1: Identify the reactants. We have 1-bromopropane, which is a molecule with a bromine atom attached to a three-carbon chain, and sodium ethoxide, which is a compound made of sodium and ethoxide ion.
Step 2: Understand what a nucleophilic substitution reaction is. In this type of reaction, a nucleophile (a species that donates an electron pair) replaces a leaving group (in this case, bromine).
Step 3: Recognize that the ethoxide ion (from sodium ethoxide) acts as the nucleophile. It will attack the carbon atom that is bonded to the bromine atom in 1-bromopropane.
Step 4: The bromine atom leaves, making it a leaving group, and the ethoxide ion takes its place, forming a new bond with the carbon atom.
Step 5: The result is a new compound called propoxyethane, where the ethoxide has replaced the bromine.
