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.

According to the given reaction:
Substrate: Cyclohexadiene
Reagent: Br2/CCl4
The given reaction is an example of electrophilic addition reaction of halogen to a conjugated diene.
Alkenes undergo electrophilic addition reaction because the double bond acts as a nucleophile and the pi-bond of the alkene can be donated to an electrophile, resulting in the formation of a new bond between the carbon bearing the double bond and the electrophile.
