write the systematic (iupac) name of each organic molecule: structure name

write the systematic (iupac) name of each organic molecule: structure name
Answer
Explanation:
Step1: Analyze first structure
The first molecule is a cyclohexane with two methyl - groups at 1 and 3 positions. So the IUPAC name is 1,3 - dimethylcyclohexane.
Step2: Analyze second structure
The second molecule is a cyclopropane with an ethyl - group attached. The IUPAC name is ethylcyclopropane.
Step3: Analyze third structure
The third molecule is a cyclopentane with an isopropyl - group at 1 position and an ethyl - group at 3 position. The IUPAC name is 1 - isopropyl - 3 - ethylcyclopentane.
Answer:
- 1,3 - dimethylcyclohexane
- ethylcyclopropane
- 1 - isopropyl - 3 - ethylcyclopentane
