METAL CARBONYLS

What is metal carbonyls? Carbon monoxide is undoubtedly one of the most important and most widely studied ligand in organometallic chemistry. Almost all of the transition metals from metal carbonyls (the complex containing only CO as ligands)and these homoleptic carbonyls are useful precursors for other organometallic compounds.Though carbon monoxide is not considered as a very strong …

Bio Inorganic Chemistry

  INTRODUCTION:          Bioinorganic chemistry is a field that examines the role of metals in biology. It is the gateway of inorganic chemistry and biochemistry i.e, it describes the mutual relationship between these two sub-disciplines, with the focus upon the function of inorganic substances in living systems, including the transport, speciation and eventually, mineralization of …

Types of Adsorption

Different types of Adsorption Adsorption may be  classified into flowing types i.e. (a) On the basis of concentration(b)On the basis of nature of force existing between adsorbate and adsorbent molecule (a)On the basis of concentration  On the basis of concentration of adsorbate, molecule adsorption can be of following two types(1)Positive Adsorption(2)Negative Adsorption (1)Positive Adsorption: If the …
