Final answer:
Skeletal structures represent organic compounds by using lines to represent carbon atoms and omit hydrogen atoms bonded to carbons. The skeletal structures for the given compounds have been identified, including common names like pyridine and 2-chloro-2-methylpropanol.
Step-by-step explanation:
The process of converting molecular formulas to skeletal structures involves representing each carbon atom with an end of a line or bend, and not drawing hydrogen atoms bonded to carbons. Here are the skeletal structures for each given compound:
- a. The compound (CH₃)2CHCH₂CH₂CH(CH₃)2 is 3-ethyl-2,4-dimethylhexane.
- b. The compound (CH₃)3C(CH₂)5CH₃ is 2,2,4-trimethylheptane.
- c. Limonene, which is not fully represented here, has a more complex structure typical of terpeηes with multiple rings and double bonds.
- d. The compound CH₃CH(Cl)CH(OH)CH₃ is 2-chloro-2-methylpropanol.
- e. The compound C₅H₅N appears to be pyridine, a six-membered ring containing one nitrogen atom.
- f. The compound CH₃(CH₂)2C(CH₃)2CH(CH₃)CH(CH₃)CH(Br)CH₃ is 5-bromo-4-ethyl-2,2-dimethylheptane.
