Question

Assertion (A): \[\ce{[Mn(CN)6]^{3−}}\] has a magnetic moment of two unpaired electrons while \[\ce{[MnCl6]^{3−}}\] has a paramagnetic moment of four unpaired electrons.

Reason (R): \[\ce{[Mn(CN)6]^{3−}}\] is an inner orbital complex involving d²sp³ hybridisation; on the other hand, \[\ce{[MnCl6]^{3−}}\] is an outer orbital complex involving sp³d² hybridisation.

Select the most appropriate answer from the options given below:

Options
