[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°.
[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.
[edit] Popular culture
The strong, unpleasant odour of H2Te was remarked upon in a scene in the Doctor Who serial The Krotons (1968/9), when it was described as "the worst smell in the world".
