How do we come to know where to place the Cl and NH3? Cant there be any other arrangement apart from these?

It can form only coordination 4 which shows cis trans isomer . For cis chlorine should be 90 degree to each other while for trans both chlorine should be 180 degree to each other . Chorine placed anywhere other then 180 degree will only have 90 degree because all four are on same plane. Not to loose marks just male chlorine next to the other chlorine to show cis isomer.

Im sure you calculated the Mr for i.
1 gram of the sample was taken so you divide the mass by Mr.
You then get the number of moles.
Which will be equal to one of the answers on the table for AgCl. Then you calculate the other values of n simply by looking at the ratios.

(These were just the steps so that you try it yourself) Good Luck.

Also Holmes this is actually the correct explanation
well you can only have two isomers
cis and trans
and for the cis isomer, there will be two optical isomers since there is also a bidentate ligand present
THIS IS TRANS

THE ONES BELOW ARE BOTH CIS AND MIRROR IMAGES OF EACH OTHER...THE LINE IN BETWEEN IS THE MIRROR
THIS KIND OF ISOMERISM IS ONLY POSSIBLE WHEN BIDENTATE LIGANDS ARE ALSO PRESENT

can u pls explain the charges on each?
Zaki ali asghar
i think phenol should ionise in such a high pH aint it?
and i think it is tyr that is P and the phe-tyr and phe are R and S
becuz like phe has a low mass and double the charge since phenol and acid both ionise
and since phe-tyr has double the mass and double the charge than tyr, the movement of both is same in the end

This one too.
well the first one shows both: optical due to bidentates and cis trans because there are pairs of two types of ligands.
the 2nd one shows only cis trans since its square planar
the 3rd one shows neither becuz the shape is tetrahedral so no cis trans and secondly not all the ligands are different so optical cant be shown either
