1. Cis-3-methyl-2-pentene: A five-carbon chain with a double bond between carbons 2 and 3, and a methyl group on carbon 3; the two hydrogens on the double bond are on the same side.
2. Trans-3-methyl-2-pentene: A five-carbon chain with a double bond between carbons 2 and 3, and a methyl group on carbon 3; the two hydrogens on the double bond are on opposite sides.
3. Cis-trans-cis 2,4,6-octatriene: An eight-carbon chain with double bonds between carbons 2–3, 4–5, and 6–7; the configuration is cis at 2–3, trans at 4–5, and cis at 6–7.
4. Cis-2,3-dimethyl-2-pentene: A five-carbon chain with a double bond between carbons 2 and 3, and methyl groups on both carbons 2 and 3; the two larger groups (methyl and ethyl) are on the same side of the double bond.
5. Trans-3-methyl-2-octene: An eight-carbon chain with a double bond between carbons 2 and 3, and a methyl group on carbon 3; the two larger groups (methyl and pentyl) are on opposite sides of the double bond.
6. 4-t-butyl-2-methylheptane: A seven-carbon chain with a methyl group on carbon 2 and a tert-butyl group on carbon 4.
7. 5-t-butyldecane: A ten-carbon chain with a tert-butyl group on carbon 5.
8. Sec-butylcycloheptane: A seven-membered ring with a sec-butyl group attached (CH(CH₃)CH₂CH₃).
9. Sec-propylcyclopentane: A five-membered ring with a sec-propyl group attached (CH(CH₃)CH₃).
10. Cis-diethylcycloheptane: A seven-membered ring with two ethyl groups on adjacent carbons, both on the same face of the ring.
11. Trans-3-hexene: A six-carbon chain with a double bond between carbons 3 and 4; the two ethyl groups are on opposite sides.
12. Cis-2-butene: A four-carbon chain with a double bond between carbons 2 and 3; the two methyl groups are on the same side.
13. Octane: A straight-chain eight-carbon alkane.
14. Trans-2,3-di-tert-butyl-2-butene: A four-carbon chain with a double bond between carbons 2 and 3, each bearing a tert-butyl group; the two tert-butyl groups are on opposite sides.
15. 4-methylheptane: A seven-carbon chain with a methyl group on carbon 4.
