I would name the first one
3-methyl-3-heptene
The others don't make sense because of the spacing problem. (We can't space on the board).
The compound you have provided can be named as follows:
2-methyl-3-hexene
Here's how to determine the name:
1. Identify the longest carbon chain in the molecule: In this case, it is a six-carbon chain.
2. Number the carbon atoms in the chain starting from one end, giving the substituents (methyl and ethyl groups) the lowest possible numbers. In this case, numbering from left to right, we have the substituents at positions 2 and 3.
3. Name the substituents in alphabetical order: In this case, we have a methyl group (CH3) and an ethyl group (CH2CH3).
4. Combine all the information to create the final name: The name is 2-methyl-3-hexene.
Note: The double bond is indicated by the "-ene" ending in the name.
I hope this explanation helps! Let me know if you have any further questions.
