Q56 · Chemistry

Which is the correct thermal stability order for H2EH_2E (E = O, S, Se, Te and Po) ?

  1. 1H2S<H2O<H2Se<H2Te<H2PoH_2S < H_2O < H_2Se < H_2Te < H_2Po
  2. 2H2O<H2S<H2Se<H2Te<H2PoH_2O < H_2S < H_2Se < H_2Te < H_2Po
  3. 3H2Po<H2Te<H2Se<H2S<H2OH_2Po < H_2Te < H_2Se < H_2S < H_2OOfficial answer
