Question

Only HF and H₂O from polymeric structure due to H-bonding. HF froms linear polymeric, whereas H₂O froms tetrahedral polymeric structure.

Answer 1

True

Answer 2

The statement claims two things: (1) Only HF and H₂O form polymeric structures due to H-bonding, and (2) HF forms linear polymeric, while H₂O forms tetrahedral polymeric structures.

1. "Only HF and H₂O form polymeric structure due to H-bonding": While NH₃ also forms H-bonds and associates, HF and H₂O are the most prominent examples among simple inorganic hydrides that form distinct and extensive polymeric networks. This part is generally considered true in the context of typical curriculum.
2. "HF forms linear polymeric, whereas H₂O forms tetrahedral polymeric structure": This is a well-established fact. HF forms zig-zag chains due to one H-bond donor and one acceptor site per molecule. H₂O forms a 3D tetrahedral network because each molecule can participate in four H-bonds (two donors, two acceptors).
