Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Among the , Chloral , Orthochlorophenol , Sodium dihydrogen phosphate , HCN, Find the total number of molecules which have hydrogen bonding.
Answer:
Solution:
NaHCO₃: Contains O-H bonds in the bicarbonate anion (HCO₃⁻) which form intermolecular hydrogen bonds.
Orthochlorophenol: The -OH group forms intramolecular hydrogen bonds with the adjacent chlorine atom.
Sodium dihydrogen phosphate (NaH₂PO₄): Contains O-H bonds attached to phosphorus that undergo intermolecular hydrogen bonding.
HCN: The highly polar nature of sp-hybridized carbon allows HCN molecules to associate via linear intermolecular hydrogen bonds (C-H⋅⋅⋅N).
(Note: K₂HPO₃ contains a non-polar P-H bond, and Chloral (CCl₃CHO) lacks H attached to F, O, or N, so neither can form hydrogen bonds).
