In oxidizing another element, a halogen is itself reduced; i.e., the oxidation number 0 of the free element is reduced to −1. The halogens can combine with other elements to form compounds known as halides—namely, fluorides, chlorides, bromides, iodides, and astatides. Many of the ...

They can be produced from an alcohol or an alkene. Alkyl Halide Structure As mentioned, the alkyl halide structure differs from alkanes due to the replacement of a hydrogen atom with a halogen atom. The structure can be classified as primary, secondary, or tertiary, based on the number of ...
摘要: PROBLEM TO BE SOLVED: To provide a method for producing a phenol alkyl ether in a high yield by bringing a phenol compound into contact with a lower aliphatic alcohol in the presence of a niobic acid in a gaseous phase to alkyl-etherify the phenol compound....
