Using Valence bond theory, explain the following in relation to the paramagnetic complex [Mn(CN)6] 3-

Question 14:Using Valence bond theory, explain the following in relation to the paramagnetic complex [Mn(CN)6]3-

a. type of hybridization b. magnetic moment value c. type of complex – inner, outer orbital complex

The correct answer is -.[Mn(CN)6]3- Mn = [Ar] 3d54s2 Mn3+ = [Ar] 3d4 Mn (ground state)

Type of hybridization – d2sp3 Magnetic moment value – √n(n+2) = √(2(2+2)) = 2.87 BM (n= no. of unpaired electrons) Type of complex – inner orbital
