Count entries with conventional INTERMOLECULAR H bonding in the specified state: NaHCO₃ crystal; KH₂PO₄ crystal; K₂HPO₃ crystal (sole H is P–H); pure HCN; pure N-methylacetamide; pure acetone; isolate

Question

Count entries with conventional INTERMOLECULAR H bonding in the specified state: NaHCO₃ crystal; KH₂PO₄ crystal; K₂HPO₃ crystal (sole H is P–H); pure HCN; pure N-methylacetamide; pure acetone; isolated gaseous methanol monomer; liquid ethylene glycol. Apply the strict N/O/F–H donor rule; distinct molecules or ions must provide the two partners.

TestHub · Accepted Answer

Bicarbonate, dihydrogen phosphate, N-methylacetamide and glycol qualify. Hydrogen phosphite has P–H, HCN is excluded by the donor rule, acetone lacks a donor, and the isolated monomer lacks a partner. Count 4.
