How many structural and geometrical isomers are there of chloropropene?

Question

Quizplus · Accepted Answer

There are two isomers of propene, and the addition of a chlorine atom can result in two structural isomers (1-chloropropene and 2-chloropropene). Additionally, each of these structural isomers can have two possible cis-trans configurations, resulting in a total of four geometrical isomers. Therefore, the total number of isomers of chloropropene is 2 structural isomers x 2 geometrical isomers per structural isomer = 4 isomers. Choice C is the only option that correctly represents this number.
