The type of hybridisation and the magnetic property of [MnCl6]3− are, respectively: (1) sp3d2, paramagnetic with two unpaired electrons (2) d2sp3, paramagnetic with two unpaired electrons (3) sp3d2, paramagnetic with four unpaired electrons (4) d2sp3, paramagnetic with four unpaired electrons

1. sp3d2, paramagnetic with two unpaired electrons
2. d2sp3, paramagnetic with two unpaired electrons
3. sp3d2, paramagnetic with four unpaired electrons
4. d2sp3, paramagnetic with four unpaired electrons

Correct answer: sp3d2, paramagnetic with four unpaired electrons

Solution

The correct option indicates that [MnCl6]3− undergoes sp3d2 hybridization, which is typical for octahedral complexes, and it has four unpaired electrons due to the presence of a d5 configuration in manganese, leading to its paramagnetic nature.
