WebThe alkynes reaction with bromine water is explained below: Both alkynes and alkanes can decolorize bromine water. The reaction of alkenes and alkynes with bromine water can be used as a visual inference for differentiating between alkanes ,alkenes and alkynes, in which alkanes do not react quickly with bromine, while alkanes and alkynes react quickly … Web2 to Alkynes Halogens add to alkenes in a way that is similar to alkenes. An analogous bromonium ion is formed in this case as well, and the subsequent attack of bromide … WebContain a carbon-carbon double bond, each carbon being sp2 hybridized and trigonal planar. Alkynes Contain a carbon-carbon triple bond, each sp hybridized and linear. True (T/F) Alkenes are more reactive than alkanes. True (T/F) Alkynes are more reactive than alkenes due to their large surface area. CnH2n+2 What is the general formula for alkanes? himalaya denise
