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.

![**Question:**
What is the expected major product of the reaction shown?
**Reaction:**
\[ \text{Ph} \underset{\large{\text{H}_3\text{C}}}{\overset{\color{red}\ominus\large{\text{Na}}^{\large{\text{+}}}}} \, \begin{array}{c}
\text{|} \\
\text{H}_3\text{C} \, \text{C} \, \text{Br}
\end{array}
\begin{array}{c}
\, \text{Ph} \\
\text{H} \,
\end{array}
\overset{\displaystyle{\large{\underset{\large{\text{CH}_3\text{O}}}}}}{\displaystyle{\longrightarrow}} \]
**Options:**
I. \(\text{PhCH=C(Ph)CH}_3\)
II. \(\text{H}_2\text{C}=\begin{array}{c}
| \\
\text{C=CH}_2 \\
| \\
\text{Ph}
\end{array} \)
III. \(\text{H}_3\text{CCH=CHPh} \)
IV. \(\text{PhCH}= \begin{array}{c}
| \\
\text{C(Ph)CH}_3
\end{array}\)
**Explanation:**
The reaction is a dehydrohalogenation of an alkyl halide in the presence of a strong base, \( \text{CH}_3\text{O}^- \text{Na}^+ \), leading to the formation of an alkene.
The correct answer is **Option III: \(\text{H}_3\text{CCH=CHPh} \)**. This is the product where elimination of HBr occurs, resulting in the formation of the most stable alkene, based on Zaitsev's rule, which states that the more substituted alkene is favored.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F23d89a6c-0130-4c26-9920-1735efafdd1c%2F4651c9fd-e536-4aca-bbd0-4ec8dad2750f%2Frggt9jj_processed.jpeg&w=3840&q=75)
