Natural rubber is a polymer of one of these molecules, which show 𝑠𝑝 2 [S  P "two"] hybridization and whose substituent positions are described with cis\- trans  notation.
One of these organic molecules forms a coordination complex with platinum in Zeise's [rhymes   with "mice's"] salt, and peroxyacids are used to convert this class of compounds to  epoxides [ee-PAHK-"sides"].  The addition of halogens to these compounds is described by   Markovnikov's rule. Natural rubber is a polymer of one of these molecules, which show 𝑠𝑝 2 [S  P "two"] hybridization and whose substituent positions are described with cis\- trans  notation. These  compounds are found in unsaturated fats like vegetable oils, and simple examples have twice as  many hydrogen atoms as carbon atoms. Name this group of organic compounds with at least one  carbon-carbon double bond.
