what is the condensed structural formula for.
5- ethyl-2-hexene
see above
To determine the condensed structural formula for 5-ethyl-2-hexene, you need to follow these steps:
1. Understand the naming conventions: In organic chemistry, the position of substituents (atoms or groups of atoms) on a hydrocarbon chain is indicated by numbers. The numbering starts from the end of the chain nearest to the substituent. The prefixes indicate the type and location of these substituents.
2. Identify the main chain: In this case, the main chain is a hexene, which means it's a six-carbon chain with a double bond.
3. Locate the substituents: The name "5-ethyl-2-hexene" indicates that there are two substituents present: ethyl (C2H5-) and methyl (CH3-) groups. The "5-ethyl" prefix indicates that the ethyl group is attached to the fifth carbon of the main chain, and the "2-hexene" indicates a double bond between the second and third carbons.
4. Write the condensed structural formula: Start by drawing the main chain of six carbons with a double bond between the second and third carbons:
CH3-CH=CH-CH2-CH2-CH3
Next, add the ethyl group (C2H5-) to the fifth carbon:
CH3-CH=CH-CH2-CH2-C2H5
That's the condensed structural formula for 5-ethyl-2-hexene.
