Questions & Step-by-Step Solutions

What is the major product of the reaction between 1-bromobutane and sodium ethoxide in ethanol?
  • Step 1: Identify the reactants. We have 1-bromobutane (a primary alkyl halide) and sodium ethoxide (a strong nucleophile).
  • Step 2: Recognize the type of reaction. This is an SN2 reaction because 1-bromobutane is a primary halide, which is favorable for SN2.
  • Step 3: Understand the role of sodium ethoxide. Sodium ethoxide (C2H5O-) will attack the carbon atom that is bonded to the bromine in 1-bromobutane.
  • Step 4: Describe the nucleophilic attack. The ethoxide ion will replace the bromine atom, forming a new bond with the carbon.
  • Step 5: Identify the product. The product formed is 1-ethoxybutane, where the ethoxy group (C2H5O-) is now attached to the butane chain.
