Question

Cr (h2o)6 +2 hybridisation

Answer 1

it's hybridisation is d2sp3 and its shape is square bipyramidal with violet colour

Answer 2

Hey dear,

● Answer -

[Cr(H2O)6]2+ shows d2sp3 hybridization.

● Explanation -
[Refer to the image for better understanding.]

Electronic configuration of Cr (Z=24) is [Ar] 3d5 4s1.

Cr loses 3e- to form Cr3+ with electronic configuration [Ar] 3d3 4s0.

Electrons from 6 water molecules fill two 3d, one 4s and three 4p orbitals.

Thus, [Cr(H2O)6]2+ shows d2sp3 hybridization.

Hope this helps you...
