Chemistry Question on coordination compounds

The geometry of Ni(CO)4 Ni(CO)_{4} and Ni(PPh3)2Cl2 Ni(PPh_{3})_{2}Cl_{2} are:

A

both square planar

B

tetrahedral and square planar respectively

C

both tetrahedral

D

square planar and tetrahedral respectively

Answer

both tetrahedral

Explanation

Solution

Ni(CO)4Ni ( CO )_{4} and Ni(PPh3)2Cl2Ni \left( PPh _{3}\right)_{2} Cl _{2} are tetrahedral in geometrical shape, because co-ordination number of NiNi is 4 in both cases.
