Final answer:
To draw the line structure for the compound CH₃CH₂CCCH(CH₃)₂, start with the parent chain and add the appropriate substituents.
Step-by-step explanation:
The compound CH₃CH₂CCCH(CH₃)₂ can be drawn as follows:
- Start with the parent chain, which is butane (four carbon atoms in a straight line): CH₃-CH₂-CH=CH(CH₃)-CH₃
- Add the appropriate substituents to the carbons. In this case, there are two methyl groups on the third carbon and a methyl group on the fourth carbon:
CH₃-CH₂-CH=(CH₃)₂-CH₃
