Match the species in Column I with their related properties in Column II.(Atomic Number is indicated in brackets in Column-I)

 

Moderate
Solution

Paramagnetic due to unpaired electron and sum of spin

=3×12=1.5

Thus, (P-1, 3)

Paramagnetic and coloured due to unpaired electrons in 3d

Sum of spin = 1.5

Thus, (Q-1, 2, 3)

Coloured and paramagnetic 

Sum of spin = 2.5

Thus, (R-1, 2)

Coloured and paramagnetic 

Sum of spin = 2.0

Magnetic moment =N(N+2)

=  4(6)

=24BM

Thus, (S-1, 2, 4)
