Q52.Consider the following reaction and statements: [Co (NH3)4 Br2]+ + Br−→[Co (NH3)3 Br3] + NH3 (i) Two isomers are produced if the reactant complex ion is a cis-isomer. (ii) Two isomers are produced if the reactant complex ion is a trans-isomer. (iii) Only one isomer is produced if the reactant complex ion is a trans-isomer. (iv) Only one isomer is produced if the reactant complex ion is a cis-isomer. The correct statements are (1) (ii) and (iv) (2) (i) and (ii) (3) (i) and (iii) (4) (iii) and (iv)
What This Question Tests
This question requires visualizing the stereochemical outcomes of a ligand substitution reaction starting from either a cis or trans isomer of an octahedral complex, leading to different isomers of the product.
