Concept explainers

Reactions of Ethers

Ethers (R-O-R’) are compounds formed by replacing hydrogen atoms of an alcohol (R-OH compound) or a phenol (C6H5OH) by an aryl/ acyl group (functional group after removing single hydrogen from an aromatic ring). In this section, reaction, preparation and behavior of ethers are discussed in the context of organic chemistry.

Epoxides

Epoxides are a special class of cyclic ethers which are an important functional group in organic chemistry and generate reactive centers due to their unusual high reactivity. Due to their high reactivity, epoxides are considered to be toxic and mutagenic.

Williamson Ether Synthesis

An organic reaction in which an organohalide and a deprotonated alcohol forms ether is known as Williamson ether synthesis. Alexander Williamson developed the Williamson ether synthesis in 1850. The formation of ether in this synthesis is an SN2 reaction.

2. CH₃CH₂CH₂Br

**Graph/Diagram Description:**
- The graphical representation (at the bottom of the image) shows a chemical structure that is the major product of the reaction. The structure features:
- A benzene ring with a substituted triple-bonded ethylene group (ethynyl group) attached at one position.
- Additionally, a 3-carbon aliphatic chain (propyl group) is connected to the terminal end of the ethynyl group.

**Instructions:**
- In the dashed box labeled "Select to Draw," students are expected to draw the corresponding starting material that would undergo the reaction with NaNH₂ (sodium amide) and CH₃CH₂CH₂Br (1-bromopropane) to form the given major product.
- The goal is to identify the appropriate starting structure that will, under the given conditions, synthesize the product shown in the diagram.

**Chemical Reaction Steps:**
1. The first reagent, NaNH₂, is typically a strong base used to deprotonate and form anions, initiating a nucleophilic substitution or elimination reaction.
2. The second reagent, CH₃CH₂CH₂Br, is used as an alkylating agent, providing a propyl group during the course of the reaction.
