QUESTION #41 Stability of Complexes and Oxide Nature
'X' is the number of electrons in mathrmt_2mathrmg orbitals of the most stable complex ion among [mathrmFe(mathrmNH_3)_6]^3+, [mathrmFe(mathrmCl_6)]^3-, [mathrmFe(mathrmC_2mathrmO_4)_3]^3- and [mathrmFe(mathrmH_2mathrmO)_6]^3+. The nature of oxide of vanadium of the type mathrmV_2mathrmO_mathrmX is:

QUESTION #48 Isomerism in Coordination Compounds
A metal complex with a formula mathrmMCell_4cdot3mathrmNH_3 is involved in mathfraksp^3mathfrakd^2 hybridisation. It upon reaction with excess of mathrmAgNO_3 solution gives 'x' moles of AgCl. Consider 'x' is equal to the number of lone pairs of electron present in central atom of mathrmBrF_5 . Then the number of geometrical isomers exhibited by the complex is
