Which of the following compound(s) has ' Z ' configuration?
Options
- A(i) only
- B(ii) only
- C(iii) only
- D(i) and (iii)
Correct answer
D. (i) and (iii)
Step-by-step solution
When the groups with higher priority (ie, with high atomic number) are present on same side of double bond, then the configuration is Z but when present on opposite side of double bond, the configuration is E . (Priority : Br > Cl and CH ₃> H ) Hence, compound (i) and (iii) have (Z) configuration.
