Question

Match the lists. LIST I LIST II (P) Fe 3 + (1) Undergoes dsp 3 hybridization to form a mononuclear carbonyl (Q) Fe 2 + (2) Forms blood-red colouration with KSCN (R) Fe 4 + (3) The spin-magnetic moment is identical to that of Fe 2 + ion (S) Fe (4) The aqueous solution of its sulphate is green coloured (5) Oxide is colorless

TestHub · Accepted Answer

Fe 3 + → Fe ( SCN ) 3 ​ Fe 2 + → Green sulphate F e 4 + ( n = 4 ) , F e 2 + ( n = 4 ) Fe → Fe ( CO ) 5 ​ hybridization ( dsp 3 )
