Alkenes:Formula,Structure, Preparation,Physical Properties & Uses

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. Comment ( 3 votes) Upvote Flag Mathilda Lewis 7 years ago 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. the preismans reviews https://boissonsdesiles.com
