Which of the following possesses hydrogen bonding? H2S, H2O, H2Se, H2Te

Answer»
  • Oxygen being more electronegative, is capable of forming hydrogen bonding in the compound H2O.
  • The other elements S, Se and Te of Group 16, being less electronegative do not form hydrogen bonds.
  • Thus, hydrogen bonding is not present in the other hydrides H2S, H2Se and H2Te.
