On the basis of Valence bond theory account for the hybridization, shape and magnetic property of cuprammonium ion. |
Answer» Solution :`Cu^(2+) ………….. [AR] 3d^94s^0`  Under the influence of approaching `NH_3` ligand an `1e^-` from 3d gets excited to 4P.  The four empty orbitals undergo dsp-hybridization to form four HYBRID orbitals of equal energy. The orbitals of the ligand which CONTAIN lone pair of electrons overlap with hybrid orbitals `Cu^(2+)` ION to form co-ordinate bond.  Shape ........ squar planar Or
