How do you test for an alkene
http://passmyexams.co.uk/GCSE/chemistry/test-for-alkenes.html WebTesting alkane & alkene with bromine water Share Watch on Note: I suspect that the two compounds are cyclohexane and cyclohexene. Cyclohexane has a ring of 6 carbon atoms with 2 hydrogens attached to each. Cyclohexene also has a ring of 6 carbon atoms, but this time there is a double-bond in the ring.

http://chemed.chem.purdue.edu/genchem/topicreview/bp/1organic/reaction.html WebTesting for alkenes The presence of the C=C double bond allows alkenes to react in ways that alkanes cannot. This allows us to distinguish alkenes from alkanes using a simple chemical...
WebE–Z notation can be used to describe the configuration of a double bond with two or more substituents.To do so, each substituent is assigned a priority using the Cahn–Ingold–Prelog rules. If the two higher priority substituents are on same side of the double bond, the configuration of the bond is Z.If the two higher priority substituents are on opposite sides … 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 are relatively stable compounds, but are more reactive than alkanes, due to the carbon-carbon π-bond reactivity. Most alkene reactions involve adding to this bond, … WebAlkenes After studying this section you should be able to: recognise the nature of cis-trans isomerism in alkenes understand that the double bond in alkenes takes part in addition reactions with electrophiles understand the …
