Web12 apr. 2024 · The [closo-B 10 H 10] 2− and [closo-B 12 H 12] 2− ions were explored by others in terms of substitution reactions and novel reactivity patterns were documented for these seemingly “aromatic” ions.Reactions which yield exclusive substitution at the 1,10 (apical) positions of [closo-B 10 H 10] 2− are rare.The dinitrogen and carbon monoxide … If an ion contains unpaired electrons, it is called a radical ion. Just like uncharged radicals, radical ions are very reactive. Polyatomic ions containing oxygen, such as carbonate and sulfate, are called oxyanions. Molecular ions that contain at least one carbon to hydrogen bond are called organic ions. Meer weergeven An ion is an atom or molecule with a net electrical charge.
