Consider the following ligands N H 2 - , a c a c , S H - , G l y , O 2 - , P h e n , D M G , N O 2 - , C O 3 2 - , I - , C H 3 C O O - , e n , S O 4 2 - . Then calculate value of "P + Q – R – S" Here, P: Total number of ligands which act as bridging as well as monodentate only. Q: Total number of flexidentate ligands R: Total number of bidentate ligands only S: Total number of unsymmetrical bidentate ligands
Correct answer
1
Step-by-step solution
P = N H 2 - , O 2 - , S H - , I - = 4 Q = S O 4 2 - , N O 2 - , C O 3 2 - , C H 3 C O O - = 4 R = e n , a c a c , P h e n , D M G , G l y = 5 S = D M G , G l y = 2 4 + 4 – 5 – 2 = 1.
