t-butyl bromide (2-bromo-2-methylpropane) undergoes an SN1 reaction (with solvent as nucleophile) in isopropyl alcohol/water mixtures. Isopropyl alcohol = CH3-CH(OH)-CH3; water = H2O; Given: water is more polar solvent than isopropyl alcohol. In which of the following solvent mixtures will t-butyl bromide react the fastest? Select one: A.50% isopropyl alcohol / 50% water B.40% isopropyl alcohol / 60% water C.70% isopropyl alcohol / 30% water D.30% isopropyl alcohol / 70% water
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.
