WebSoft Lewis acids and bases are relatively large, polarizable atoms, ions, and molecules. Hard Lewis acids and bases are relatively small and less polarizable . In practice, soft …
WebSoft bases are electron-pair donors--Lewis bases--in which the donor atom, similar to a soft acid, has a high polarizability. Hard bases have a donor atom with the opposite characteristics. For example, a metal in a low oxidation state, such as Ni (0), is a soft acid that is stabilized when surrounded by soft bases, such as CO in Ni (CO) 4. Web“Hard acids prefer to bind (co-ordinate ) with hard bases and soft acids prefer to bind with soft bases and gives stable complex compound ”. It should be noted that the statement given above is not a theory or an explanation but it is simple rule of thumb which enables us to predict the relative stabilities of acid-bases adducts ...
