For the cycloaddition reaction shown below A B NC CN a) Give the curved arrow-pushing and draw the allowed product for the reaction, be sure to include stereochemistry and indicate any racemic mixtures b) on TOP of reactant A draw a pictorial representation of the HOMO (draw it on the structure like the one shown below rather than the one in the equation so that the curved arrow-pushing isn' obscured) A heat c) on TOP of reactant B draw a pictorial representation of the LUMO (draw it on the structure below rather than the one in the equation so that the curved arrow-pushing isn't obscured) B NC CN
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.
