The cyanide ion is a reductant and is oxidized by strong oxidizing agents such as molecular chlorine (Cl 2), hypochlorite (ClO −), and hydrogen peroxide (H 2 O 2). These oxidizers are used to destroy cyanides in effluents from gold mining .
Any salt containing the ion, such as ammonium cyanate, is called a cyanate. The cyanate ion is an isomer of the much-less-stable fulminate anion, CNO − or [C − ≡N + −O −]. [1] The cyanate ion is an ambidentate ligand, forming complexes with a metal ion in which either the nitrogen or oxygen atom may be the electron-pair donor.
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
Cyanogen azide is a chemical compound with the chemical formula C N 4, or more precisely − N=N + =N−C≡N.It is an azide compound of carbon and nitrogen.It is an oily, colourless liquid at room temperature. [2]
Pentacyanocobaltate ([Co(CN) 5] 3−) is produced by the addition of five or more equivalents of a cyanide to a solution of a cobalt(II) salt. It is square pyramidal. [ 5 ] Solutions of [Co(CN) 5 ] − 3 undergo a variety of reactions, such as hydrogenation: [ 6 ]
The heaviest isotope produced by direct fusion is 283 Cn; the three heavier isotopes, 284 Cn, 285 Cn, and 286 Cn, have only been observed as decay products of elements with larger atomic numbers. [78] In 1999, American scientists at the University of California, Berkeley, announced that they had succeeded in synthesizing three atoms of 293 Og. [81]
A CN bond is strongly polarized towards nitrogen (the electronegativities of C and N are 2.55 and 3.04, respectively) and subsequently molecular dipole moments can be high: cyanamide 4.27 D, diazomethane 1.5 D, methyl azide 2.17, pyridine 2.19. For this reason many compounds containing CN bonds are water-soluble.
Potassium dicyanoargentate is an inorganic compound with the formula KAg(CN) 2. A white solid, it is the K + salt of the linear coordination complex [Ag(CN) 2 ] − . It forms upon treatment of virtually any silver salt with two equivalents of potassium cyanide .
