What the name : CH2 CH CH (CH3) CH2 C (CH3)2 CH3
It maybe an alkene, but it looks like you have typos.
You sure there's a CH3 in the middle like that?
It's usually at one end, since only a single valence electron is free on the C atom.
The name you provided is a chemical formula. To properly identify the compound, we need to convert this chemical formula into a systematic name using the IUPAC nomenclature rules. Here's how you can do it:
1. Begin by identifying the longest continuous carbon chain in the molecule. In this case, we have a chain with eight carbon atoms.
CH2 - CH - CH - (CH3) - CH2 - C - (CH3)2 - CH3
2. Write the name of the chain using the appropriate prefix. In our case, the chain has eight carbon atoms, so it is called octane.
3. Number the carbon atoms in the chain starting from the end closest to the first branch. In our case, both branches are attached to the 4th carbon atom, so we'll start numbering from one end.
CH2 - CH - CH - (CH3) - CH2 - C - (CH3)2 - CH3
|----- 4 ------|
4. Now, we describe the branches using appropriate prefixes and place them in alphabetical order.
- (CH3) is a methyl group, so we write it as 4-methyl.
- (CH3)2 is two methyl groups attached to a central carbon atom. It is called dimethyl, and since it is also attached to the 4th carbon, we write it as 4,4-dimethyl.
5. Combine all the information to form the systematic name. In this case, the name is 4,4-dimethyl-4-propylheptane.
So, the name corresponding to the given chemical formula CH2 CH CH (CH3) CH2 C (CH3)2 CH3 is 4,4-dimethyl-4-propylheptane.
