Hydrogen telluride
From Wikipedia, the free encyclopedia
Hydrogen telluride is the chemical compound with the formula H2Te. It is the simplest hydride of tellurium.
[edit] Physical description
Most compounds with Te-H bonds are unstable with respect to loss of H2, and H2Te follows this pattern. H2Te is chemically similar to hydrogen selenide, both are reactive, acidic species with H-X-H angles approaching 90°.
- Melting point: −49 ℃
- Boiling point: −2 ℃
- Molar mass: 129.62 g mol−1
[edit] Synthesis
H2Te is prepared by the acidification of salts of Te2−, such as Al2Te3 and Na2Te. Na2Te can be generated by the reaction of Na and Te in anhydrous ammonia.
