Q11 / 91 · KVPY 2020 (SB/SX) · Chemistry

The magnetic moment (in $μ_{B}$ ) of $[Ni (dimethylglyxoimate)_{2}]$ complex is closest to:

A
$5.37$
Correct answer
B
$0.00$
C
$1.73$
D
$2.25$

Solution

$[Ni (dmg)_{2}]$
${Ni}^{2 +}$
${dmg}^{- 1} SFL$

No unpaired electron present in last $' d'$ orbital
$∴$ diamagnetic $(μ_{B} = 0)$

Hence, the correct answer is option: 'B'.
