\___/ hexane with a double bong in position 1-2 with 2 ch3 one on top one on bottom what would be the name of this

I can't tell from your drawing anything about this. Is it supposed to be a cyclic compound? I hope you received my note about the earlier diiodide compound being trans and not cis.

its a hexane theres a double bond in position 1-2 with two ch3 methyls attached one methyl on top one on bottom

its a hexane theres a double bond in position 1-2 with two ch3 methyls attached one methyl on top one on bottom but where are the methyls attached? To carbon 1 or another place? If both are attached to c1 then it is a heptene.

So it's (CH3)2C=CHCH2CH2CH2CH3
This would be named 1-methyl-2-heptene but I may have guess wrong on the placement of the CH3 groups.

To name the compound, we need to determine its systematic IUPAC name based on the given structure.

In this case, we have a hexane molecule with a double bond between carbon atoms 1 and 2, and two methyl groups (CH3) attached to those carbon atoms, one on top and one on the bottom.

Let's break it down step by step:

1. Start by identifying the parent chain: Hexane has six carbon atoms, so that is our parent chain.

2. Determine the location of the double bond: The double bond is between carbon atoms 1 and 2. We need to indicate this in the name.

3. Add the substituents: We have two methyl groups (CH3), one attached to carbon atom 1 and the other to carbon atom 2.

4. Label the substituents: Since the methyl groups are located on atoms 1 and 2, we use the prefixes "1-methyl" and "2-methyl" to indicate their positions on the parent chain.

Combining all the information, we arrive at the IUPAC name for this compound:

1-Methyl-2-methylhex-1-ene.

Please note that in the name, we include the double bond (ene) as it is the highest priority functional group. Additionally, the numbering of the parent chain is determined by locating the double bond in the lowest possible position.

I hope this helps!
