Which of the following compounds (s) has Z configuration? I. II. – InterviewSolution

1.	Which of the following compounds (s) has Z configuration? I. II. III.
Answer» Only I Only II Only III I and III Solution :When the groups with higher priority (i.e. 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 : `Cl gt H` and `Br gt F`) (ii) (Priority : `Cl gt H` and `Br gt F`) (Priority : `Br gt Cl` and `CH_(3) gt H)` HENCE, compounds (i) and (iii) have (Z) configuration.
