Arrange the following alcohols in order of increasing rate of reaction with the Lucas reagent. OH HO HO OH 2-methyl-2-buta 3-butenol benzyl alcohol 2-butenol phenol nol Trehalose and isomaltose are both dimers of glucose. However, they have considerably different reactivities. Concisely explain why these differences are observed. он HO но Но. но но он HO но он но HO trehalose isomaltose 1. Isomaltose is a reducing sugar while trehalose is not. 2. Trehalose is very resistant to acid hydrolysis while isomaltose can be acid-hydrolyzed with ease.
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.
