Match the complex ions given in Column I with the hybridisation and number of unpaired electrons given in Column II and assign the correct code: Column I (Complex ion) Column II (Hybridisation, number

Question

Match the complex ions given in Column I with the hybridisation and number of unpaired electrons given in Column II and assign the correct code:

Column I (Complex ion)	Column II (Hybridisation, number of unpaired electrons)
P. [Cr(H₂O)₆]³⁺	1.dsp², 1
Q. [Co(CN)₄]²⁻	2.sp³d², 5
R. [Ni(NH₃)₆]²⁺	3.d²sp³, 3
S. [MnF₆]⁴⁻	4.sp³, 4
	5.sp³d², 2
