Magnetic moment (spin only) of octahedron complex having CFSE=- 0.8Delta_(0) and surrounded by weak field ligands can be:

Select correct statement(s) regarding octahedron complex having CFSE =-1.2Delta_(0) .

When degenerate d-orbitals of an isolated atom/ion come under influence of magnetic field of ligands, the degeneray is lost. The two set t_(2g)(d_(xy),d_(yz),d_(xz)) and e_(g) (d_(x^(2))-d_(x^(2)-y^(2)) are either stabilized or destabilized depending upon the nature of magnetic field. it can be expressed diagrammatically as: Value of CFSE depends upon nature of ligand and a spectrochemical series has been made experimentally, for tetrahedral complexes, Delta is about 4/9 times to Delta_(0) (CFSE for octahedral complex). this energy lies in visible region and i.e., why electronic transition are responsible for colour. such transition are not possible with d^(0) and d^(10) configuration. Q. The extent of crystal field splitting in octahedral complexes of the given metal with particular weak field ligand are:

A d-block element forms octahedral complex but its spin magnetic moment remains same either in strong field or in weak field ligand. Which of the following is/are correct ?

Consider that a d^(6) metal ion (M^(2+)) forms a complex with aqua ligands , and the spin only magnetic moment of the complex is 4.90 BM . The geometry and the crystal field stabilization energy of the complex is :

Velence bond theroy describes the bonding in complexs in terms of coordinate -covalent bond resulting from overlap filled ligand orbitals with vacant metal hybrid orbitals This theory explains magnetic behaviour and geometrical shape of coordination compounds Magnetic moment of a complex compound can be determined experimentally and theoretically by using spin only formula Magnetic moment sqrtn (n+2)BM (where n = No. unpaired electrons) . The value of of spin only magnetic moment for octahedral complex of the following configuration is 2.84BM The correct statement is (a) d^(4) (in weak field ligand) (b) d^(2) (in weak field and in strong field ligand) (c) d^(3) (in weak field and in strong field ligand) (d) d^(5) (in strong field ligand) .

STATEMENT-1: Tetrahedral complexes are always high spin complexes . STATEMENT-2: Crystal field splitting energy in tetrahedral complexes is 2/3 of the Delta_(0) (crystal field splitting energy in octahedral complexes). STATEMENT-3: Tetrahedral complex [MABCD]^(pm n) is optically active .

The highest value of the calculated spin-only magnetic moment (in BM) among all the transition metal complexes corresponds to x unpaired electrons in transition metal ion. The numerical value of x is _________.

The crystal field splitting energy for octahedral (Delta_(0)) and tetrahedral (Delta_(t)) complexes is related as .
