What is the name of the following organic compound?

CH_3CH_2CCCH_2CH_2CH_3

CH3CH2-C=C-CH2CH2CH3

I am assuming there is a double bond is between the carbons that are not linked to any hydrogens

count the number of carbons: 7
so, heptene

whenever there's a double, you would end with -ene (instead -ane [single bonds only])

note where the double bond is; count the carbons from left to right or right to left until you hit the double bond, depending which will give the lower number

3-heptene (the 3 denotes where the double bond is)

To determine the name of the organic compound CH₃CH₂CCCH₂CH₂CH₃, we need to follow a set of steps based on the IUPAC nomenclature rules for naming organic compounds.

Step 1: Find the longest carbon chain.
Count the number of carbon atoms in the molecule. In this compound, the longest carbon chain contains 6 carbon atoms.

Step 2: Identify any functional groups.
Identify any functional groups or substituents in the molecule. In this case, we don't have any functional groups other than the carbon chain itself.

Step 3: Number the carbon atoms.
Assign a number to each carbon atom in the longest carbon chain. Start from one end and proceed to the other, numbering in such a way that the functional group, if any, receives the lowest possible number.

In this compound, we have a continuous carbon chain with no branching or functional groups. Hence, numbering doesn't make a difference in this case.

Step 4: Name the substituents.
Identify and name any substituents attached to the main carbon chain. A substituent is any atom or group of atoms that replaces a hydrogen atom on the carbon chain.

In this compound, there is a triple bond (CC) between the second and third carbon atoms in the chain. The substituent on the first carbon atom is an ethyl group (CH₃CH₂-), and the substituent on the fourth carbon atom is also an ethyl group (CH₂CH₃).

Step 5: Combine the names.
Combine the names of the substituents with the name of the main carbon chain, placing the substituent names in alphabetical order. Separate them by hyphens and use commas to separate numbers.

In this compound, the name of the main carbon chain is hexane. The substituents are ethyl (on the first and fourth carbon atoms) and the triple bond (CC) between the second and third carbon atoms.

Therefore, the name of the organic compound CH₃CH₂CCCH₂CH₂CH₃ is 2,3-diehtylhex-1-yne.
