Name the compounds
CH3CH2CHCH2CH3
- Is this 3-Pentane? Thanks
3-Pentene **
CH3CH2CH2CH2CH3 is n-pentane.
CH3CH2CHCHCH3 is 2-pentene. You have a pentavalent C on C #2 from the right end. Counting from the left it is 3-pentene but counting from the right it is 2-pentene. Which end do you start counting? The one that gives the smaller numbers.
To determine the name of the compound CH3CH2CHCH2CH3, we need to follow the rules of IUPAC nomenclature.
First, let's count the number of carbon atoms in the longest continuous chain. In this case, there are five carbon atoms, so the root of the name will be pent-.
Next, we need to identify any branching on the main chain. Here, there is a methyl (CH3) group attached to the second carbon atom. We indicate this as a "2-methyl" group.
Putting it all together, the compound CH3CH2CHCH2CH3 is named 2-methylpentane since we have a methyl group attached to the second carbon atom of the pentane chain.
So, the correct name for this compound is 2-methylpentane.
