Draw structural formulas for the alkoxide ion and the alkyl(aryl) bromide that may be used in a Williamson synthesis of the ether shown. 10—CH,CH,CH3 H3C
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.

• Use the wedge/hash bond tools to indicate stereochemistry where it exists.
. Do not include counter-ions, e.g., Na+, I, in your answer.
• Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom
right corner.
Separate structures with + signs from the drop-down menu.
