Final answer:
The condensed formula for 3-ethyl-2-methyl-5-propylcyclopentane is C8H15(CH2CH3)(CH3)(C3H7), representing the cyclopentane ring with an ethyl, methyl, and propyl group attached at positions 3, 2, and 5, respectively.
Step-by-step explanation:
The condensed formula for 3-ethyl-2-methyl-5-propylcyclopentane involves writing out the parent chain, which in this case is cyclopentane, and then detailing the substituent groups directly attached to it without providing the full structural details for each substituent. In this case, we have an ethyl group attached to carbon 3, a methyl group attached to carbon 2, and a propyl group attached to carbon 5 of the cyclopentane ring. Substituents are listed in numerical order, and hyphens are used to separate numbers and commas to separate multiple numbers. The condensed formula does not display the structure of the molecule explicitly but provides information about the arrangement of the carbon framework and its substituents.
For the given molecule, the condensed formula would be C8H15(CH2CH3)(CH3)(C3H7). This formula indicates the base cyclopentane molecule (C8H15) and shows that there's an ethyl group (CH2CH3), a methyl group (CH3), and a propyl group (C3H7) attached to the specified carbon atoms.
