- I need to rank the alcohols in order of increasing reactivity when dehydrated with H2SO4Besides the tert-butyldimethylsilyl ethers, thereare many other widely used alcohol protecting groups. For example, analcohol such as cyclohexanol can be converted to a methoxy methylether (a MOM protecting group) by treatment with base and chloromethylmethyl ether, ClCH2OCH3. The protecting group can be removed bytreatment with aqueous acid. What functional group comprises a MOM ether?4-Methylphenol, CH3C6H4OH (pKa 10.26), is only slightly soluble in water, but its sodium salt, CH3C6H4O- Na+, is quite soluble in water.
