    The CFSE for octahedral. is 18,000 . The CFSE for tetrahedral -willbe (a) 18,000 cm-1                   (b) 16,000 cm-1    (c) 8,000 cm-1                    (d) 20,000 cm-1

Answer:

                    (c) CFSE for octahedral and tetrahedral complexes are closely related to each other by formula . where,  = CFSE for octahedral complex,  = CFSE for tetrahedral complex According to question,   = 18,000cm-1                       Hence, correct choice is (c).
