CHEMICAL PROPERTIES OF TETRAHYDROFURAN
Definition of Chemical Property
A chemical property is a characteristic or behavior of a substance that may be observed when it undergoes a chemical change or reaction. Chemical properties are seen either during or following a reaction since the arrangement of atoms within a sample must be disrupted for the property to be investigated. This is different from a physical property, which is a characteristic that may be observed and measured without changing the chemical identity of a specimen.

Chemical Properties of Ether
Ethers are quite stable compounds. They do not react with KMnO4, LiAlH4, or KOH. Ethers are basic compounds because of the unshared electron pairs on oxygen. Tetrahydrofuran is a family of ether. So THF can react with ether's reaction.
- Formation of Peroxide (Air-oxidation) Ethers slowly react with oxygen from the air to form explosive peroxides.
- Cleavage of Ethers by Acids Ethers undergo cleavage by strong acids (HI or HBr) at high temperatures to give an alcohol and alkyl halide.
- Reaction with PCl5 Ethers react with phosphorus pentachloride to form alkyl chlorides.
- Formation of Oxonium Salts Ethers react with cold concentrated H2SO4 or HCl to form oxonium salts. Ethers donate a pair of electrons to form these salts. The oxonium salts onceformed are soluble in the acid solution. The ethers can be regenerated from the oxonium salts by treatment with water.
Note : Tetrahydrofuran can only do first and second reaction.
