WebNov 5, 2024 · The IUPAC name of alkenes is obtained by using the following rules: Select the longest and continuous chain of carbon atoms containing a carbon-carbon double bond. Number the carbon atoms from that end that nearest to the double bond. Count the number of carbon atoms in the selected chain. WebAlkenes and Alkynes. Unsaturated hydrocarbons such as alkenes and alkynes are much more reactive than the parent alkanes. They react rapidly with bromine, for example, to add a Br 2 molecule across the C=C double bond. This reaction provides a way to test for alkenes or alkynes. Solutions of bromine in CCl 4 have an intense red-orange color.

WebYou make an alkyne by removing HBr, not Br₂. So you first have to add the two hydrogen atoms with H₂/Lindlar. Then, reaction with NaNH₂/NH₃ removes 2 mol of HBr and the terminal H to give CH₃CH₂C≡C:⁻. Further reaction with CH₃Br gives pent-2-yne.
