1. What Do You Mean By Disproportionation Reaction ?
Ans: It is a redox reaction ( just similarly ) where a molecule, atoms or ions can at the same time be simultaneously oxidized and reduced. In the above attachment, It shows a disproportionation reaction because 'O' ( O – it is a symbol of oxygen ) is reduced in forming H2O and oxidized in forming O2. ( here , oxygen shows an disproportionation element ). Disproportionation reaction also known as Dismutation reaction.
2. What Are Transition Elemnets And How IUPAC is stated it ?
Ans: Any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table, e.g. iron, manganese, chromium, and copper. Chemically they show variable valency and a strong tendency to form coordination compounds, and many of their compounds are coloured. In chemistry, the term transition metal has three possible definitions: The IUPAC definition defines a transition metal as "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete d sub-shell".
