Assertion (A): \([Mn(CN)_6]^{3-}\) has a magnetic moment of two unpaired electrons while \([MnCl_6]^{3-}\) has a paramagnetic moment of four unpaired electrons.
Reason (R): \([MnCN_6]^{3-}\) is inner orbital complexes involving \(d^2sp^3\) hybridisation,on the other hand, \([Mn(Cl)_6]^{3-}\) is outer orbital complexes involving \(sp^3d^2\) hybridisation.
a. Both A and R are true and R is the correct explanation of A
b. Both A and R are true but R is not the correct explanation of A.
c. A is true but R is false.
d. A is false but R is true.
