Options:

Correct Answer: Butyl ethyl ether

Exam Year: 2020

Solution:

The reaction of 1-bromobutane with sodium ethoxide leads to the formation of butyl ethyl ether through an SN2 mechanism.

What is the product of the reaction between 1-bromobutane and sodium ethoxide in ethanol? (2020)

Step 1: Identify the reactants. We have 1-bromobutane (a molecule with a bromine atom attached to a butane chain) and sodium ethoxide (a strong base and nucleophile).
Step 2: Understand the reaction type. This reaction is an SN2 reaction, which means it involves a nucleophile attacking an electrophile in a single step.
Step 3: Recognize the nucleophile. Sodium ethoxide (C2H5O-) will act as the nucleophile that attacks the carbon atom in 1-bromobutane that is bonded to the bromine atom.
Step 4: Describe the attack. The nucleophile (sodium ethoxide) attacks the carbon atom, displacing the bromine atom and forming a new bond.
Step 5: Identify the product. The result of this reaction is butyl ethyl ether, which is formed by the combination of the butyl group from 1-bromobutane and the ethyl group from sodium ethoxide.
