The geometry of Ni(CO)_4 and Ni(PPh_3)_2 Cl_2 are :

The geometry of Ni(CO)4\mathrm{Ni}(\mathrm{CO})_4 and Ni(PPh3)2Cl2\mathrm{Ni}\left(\mathrm{PPh}_3\right)_2 \mathrm{Cl}_2 are :

Options

  1. Aboth square planar
  2. Btetrahedral and square planar respectively
  3. Cboth tetrahedral
  4. Dsquare planar and tetrahedral respectively

Correct answer

C. both tetrahedral

Step-by-step solution

Ni(CO)4\mathrm{Ni}(\mathrm{CO})_4 and Ni(PPh3)2Cl2\mathrm{Ni}\left(\mathrm{PPh}_3\right)_2 \mathrm{Cl}_2 are tetrahedral in geometrical shape, because co-ordination number of Ni is 4 in both cases.
