What is the formula for an alkene containing a single C=C? CnH2n What are Alkynes? unsaturated hydrocarbons that contain triple bonds What's the general formula for an alkyne with a single triple bond?s CnH2n-2 Alkenes are sometimes called? olefins, a historical term Alkynes are sometimes called? acetylenes, a term derived from the name of the simplest alkyne IPUAC rules of naming alkenes and alkynes I. Select the longest continuous chain of carbons that contains both carbons of the C=C or the C≡C. This will form the parent name of the compound. 2. Number the carbons of the parent chain so that the carbon atoms in the multiple bond have the lowest possible numbers. 3. If the multiple bond is equidistant from either end of the chain, number from the end closest to the first branch point. Branches (alkyl substituents) are named in the usual way. 4. Indicate the position of the multiple bond using the lower of the two carbon numbers. 5. If there is more than one double bon
