Which is true for the complex `[Ni(en)_2]^(2+)` ?

Options

A. Paramagnetism, `dsp^(2)`, square planar, coordination number of `Ni=2`
B. Diamagnetism, `dsp^(2)`, square planar, coordination number of `Ni=4`
C. Diamagnetism, `sp^(3)`, tetrahedral, coordination number of `Ni=4`
D. Paramagnetism, sp^(3), tetrahedral, coordination number of `Ni=4`

Answer

B

Explanation

`[Ni(en)_(2)]^(2+) implies dsp^(2)`, square planar,
`d^(8) to ` diamagnetic
