Pick out the correct statement with respect to `[Mn(CN)_(6)]^(3-)`:

It is `dsp^(2)` hybridised and square planar

It is `sp^(3)d^(2)` hybridised and octahedral

It is `sp^(3)d^(2)` hybridised and tetrahedral

It is `d^(2)sp^(3)` hybridised and octahedral

Verified by Experts

The correct Answer is:

`[Mn(CN)_(6)]^(3-)`
`x+6(-1)=-3`
`x-6=-3`
`x=-3+6impliesx=+3`

In presence of `CN^(-)` causes pairing

`therefore d^(2)sp^(3)` is required
Hence, it is octahedral in shape.

Pick out the correct statement with respect to [Mn(CN)_(6)]^(4-)

It is `d^(2)sp(3)` hybridised and octahedral

It is `dsp^(2)` hybridised and square planar

It is `sp^(3)d(2)` hybridised and octahedral

a,b,d correct

a,c,e correct

a,c correct

b,e correct

diffraction is exhibited by all electromagnetic waves but not by mechanical waves

diffraction cannot be observed with a plane polarized light

the limit of resolution of a microscope decreases with increases in the wavelength of light used

the width of central amximum in the diffraction pattern due to single slit increases as wavelength increases
