select the molecule that corresponds to (2z)-2,5 - dichlorohex - 2 - ene.
select the molecule that corresponds to (2z)-2,5 - dichlorohex - 2 - ene.
Answer
Explanation:
Step1: Understand the IUPAC name
The name (2Z)-2,5 - dichlorohex - 2 - ene indicates a 6 - carbon chain (hex -) with a double bond at the 2 - position (hex - 2 - ene), and chlorine atoms at the 2 - and 5 - positions. The 'Z' configuration at the double bond means that the higher - priority groups on each carbon of the double bond are on the same side.
Step2: Analyze the options
Check each option for the correct number of carbon atoms, the position of the double bond, the position of the chlorine atoms, and the Z - configuration of the double bond.
Answer:
The molecule with the double - bond at the second carbon, chlorine atoms at the second and fifth carbons, and the appropriate Z - configuration of the double bond (higher - priority groups on the same side of the double bond) is the correct one. Without specific labels for each option, it's not possible to directly point out which one of the given structures is correct, but by following the above - mentioned criteria for the IUPAC name, one can identify the correct structure.
