Common names of ethers simply give the names of the two alkyl groups bonded to oxygen and add the word etherThe current practice is to list the alkyl groups in alphabetical order t-butyl methyl ether but older names often list the alkyl groups in increasing order of size methyl t-butyl etherIf just one alkyl group is described in the name it implies two.
Youll get a new ether t butyl methyl ether. Oil Contaminated Rags Filters. For example t-butyl methyl ether ethyl methyl ether If only one alkylaryl group is shown in the name of a particular ether it implies two identical groups as in ethyl ether for diethyl ether.
A Williamson involves deprotonating an alcohol to give an alkoxide and then having that react with an alkyl halide to give a new ether. The t-butyl ester tends to be more expensive.
