Final answer:
The incorrect IUPAC names '2-ethylhexane' and '3-butyl-7-methyloctane' are due to incorrect carbon chain lengths and positions of substituents. The correct IUPAC names are '3-ethylheptane' and '5-butyl-2-methylnonane', which reflect the longest carbon chain with substituents in the appropriate positions.
Step-by-step explanation:
The IUPAC names provided are incorrect due to the misplacement of substituent indicators and the lack of using the lowest numbers possible to describe the positions of the substituents and double bonds in the carbon chain.
For example, the name "2-ethylhexane" is incorrect because when naming alkanes, the main carbon chain should be the longest possible sequence of carbon atoms.
The name suggests a seven-carbon chain (hexane) with an ethyl group on the second carbon, which is not possible.
The correct IUPAC name should reflect the longest carbon chain, in this case, an eight-carbon chain which is octane, and the ethyl group should be at the third position, which results in the name 3-ethylheptane.
Similarly, the name "3-butyl-7-methyloctane" is incorrect because the longest carbon chain can only be as long as seven carbons with those substituents, not eight.
Therefore, the correct IUPAC name should be 5-butyl-2-methylnonane, as it makes the methyl group at the second position of the nonane chain.
Explain why each of the following names is an incorrect TUPAC name and write the correct IUPAC name for the intended compound: () 1,3-Dimethylbutane The name is incorrect because The correct IUPAC name is (b) 4.Methylpentane The name is incorrect because The correct IUPAC name is (c) 2,2-Diethylbutane The name is incorrect because The correct IUPAC name is (d) 2-Ethyl-3-methylpentane The name is incorrect because The correct IUPAC name is (e) 2-Propylpentane The name is incorrect because The correct IUPAC name is () 2,2-Diethylheptane The name is incorrect because The correct IUPAC name is (o) 2,2-Dimethylcyclopropane The correct IUPAC name is The name is incorrect because (h) 1-Ethyl-5-methylcyclohexane The correct IUPAC name is The name is incorrect bed because
