Final answer:
When 2-propyl-1-pentene is treated with NBS and UV light irradiation, three monobrominated compounds are produced. Isomer 1 has adjacent bromine substitutions, Isomer 2 has bromines 1 carbon apart, and Isomer 3 has bromines 2 carbons apart.
Step-by-step explanation:
When 2-propyl-1-pentene is treated with NBS (N-bromosuccinimide) and UV light irradiation, three monobrominated compounds are produced. Let's analyze each isomer:
The first isomer has two bromine substitutions adjacent to one another. This means the two bromine atoms are directly connected to each other. The second isomer has two bromine atoms that are 1 carbon apart, meaning there is one carbon atom between the two bromine atoms. The final isomer has two bromine atoms that are 2 carbons apart, meaning there are two carbon atoms between the two bromine atoms.
So, the structures that are examples of the monobrominated compounds produced are:
Isomer 1:
Structure 1: Adjacent bromine substitutions
Structure 2: Bromines written out
Isomer 2:
Structure 3: Bromines 1 carbon apart
Structure 4: Bromines written out
Isomer 3:
Structure 5: Bromines 2 carbons apart
Structure 6: Bromines written out
