(a)
Interpretation:
The structure of complex pentamminenitrito-N-cobalt(III)ion needs to be drawn.
Concept introduction:
The structure of chelate complex is formed in such a way that the ligands are linked through covalent bonds wherein the metal ion is at the centre with ligands on either side of the metal ion.
The structures gets arranged to give a square planar, octahedral or tetrahedral sturcutre. Structures gets arranged to form a stable or symmetrical geometry.
(b)
Interpretation:
The structure of chelate complex ethylenediaminedithiocyanato-S-copper(II) needs to be drawn.
Concept introduction:
Structure of chelates are formed in such a way that multidentate ligands uses more that one atom to bind to a metal ion wherein the ligands are attached to the central atom. It is mostly in the form of rings or have square planar and tetrahedral structures. The geometry needs to be stable and hence, the molecules undergo rearrangement.
(c)
Interpretation:
The structure of hexaaquanickel(II) ion needs to be drawn.
Concept introduction:
Chelate indicates those structure which are cyclic in nature and metal ions unite with organic or inorganic molecules. The presence of mulitdentate ligands uses more atoms to bind to metal ion where ligands get attached to the central atom. The structure is mostly in the form of rings. The structure is
either square planar or tetrahedral. The geometry needs to be stable for which the molecules undergo rearrangement.
