Answer 1

Sole Gliven data, trans - Feclą (appe)z is a green Colour Compound. This Compound with Washa Using reduction And Orange Colored trans Fetta (appeda result wabta toans - Fecla Cappe) Green Colour toons Fetta Cappe). - Orange Colour Phapa Pph3 by dentated ligand. s **quitorial 1 axial ligand CI Toans -- Oxelahedrool Green Colour Reason Bi dentated ligand is more bulky nature Substitud ph group present

axial cl atoms are more Crowding with bidentated ligand. So axial bonds are more Depulsion Two cl atoms are for away from planer. ve It is also Jahn-teller effect tagy ega ' It S also Erist 19ke. → Dah Symmetry. -> So, that is Squase bi pyramidal shape. I tot €94itorial axial K Orange colour Reason: . axial, Equatorial bonds are close to each others at is almost Exist an octahedral No axial Equatorial Depulsion taga ega 45a elections are present- a. shaghtly Jahn-teller effect and also out non 3de Poesent a d-d transition occub.
