(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 corr
Options
- A(ii) and (iv)
- B(i) and (ii)
- C(i) and (iii)
- D(iii) and (iv)
Correct answer
C. (i) and (iii)
Step-by-step solution
From the below image it is clear that two isomers are produced if the reactant complexion is a cis-isomer, as well as only one isomer, is produced if the reactant complex is a trans-isomer. Two isomers are produced if the reactant complex ion is a cis-isomer because the cis isomer can further form facial and meridional isomers. Only one isomer is produced if the reactant complex ion is a trans-isomer because it cannot form any isomeric isomers. Trans → only meridonial Cis → fac and mer
