Web1. (9) The equilibrium constant for the reaction: HONO (aq) + CN-(aq) D HCN (aq) + ONO-(aq) is 1.1 x 10 6. From the size of the equilibrium constant, one can conclude that a) ONO-is a stronger base than CN b) HCN is a stronger acid than HONO c) HONO is a stronger acid than HCN d) CN-is a stronger acid than HONO e) ONO-is a stronger acid than HCN- WebAnother important property shown by it is that of tautomerism. HCN also has a tautomer named hydrogen isocyanide (HNC). The concept of tautomerism is of great importance in organic chemistry. Another concept explained by HCN and HNC is ambident nucleophiles which are again commonly discussed in organic synthesis.

It is covered in A-levels, Scottish Highers and International Baccalaureate but also in all undergraduate chemistry … WebThe reagent removes pairs of H atoms from organic molecules. The stoichiometry of its action is illustrated by the conversion of tetralin to naphthalene: 2 C 6 Cl 2 (CN) 2 O 2 + C 10 H 12 → 2 C 6 Cl 2 (CN) 2 (OH) 2 + C 10 H 8. The resulting hydroquinone is poorly soluble in typical reaction solvents (dioxane, benzene, alkanes), which ...
