What is the order of reactivity of hydrogen halides with alkenes?
The correct order of reactivity of addition of hydrogen halides with alkene is: HBr>HF>HCl>HI.
What is the order of reactivity of hydrogen halides?
The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive).
Which alkene has the highest rate of reaction with HCl?
The alkene which reacts fastest with HCl is d).
Which one is the correct order of reactivity of different types Ofalcohol towards hydrogen halide?
3° alcohol > 2º alcohol > 1° alcohol.
Which is most reactive towards HBr?
-In compound (b) the oxygen atom is directly attached to the double bonded carbon atom. It will be most reactive towards HBr as the carbocation formed will be resonance stabilized. Oxygen contains 2 lone pairs.
Which one is the most reactive towards HBr?
It is a nucleophilic substitution reaction, 1- phenyl -1- propanol will be most reactive because of formation of more stable benzyl type of carbocation.
Which of the hydrogen halide HX is more reactive with alkene?
When treated with HX alkenes form alkyl halides. Hydrogen halide reactivity order : HI > HBr > HCl > HF (paralleling acidity order). Reaction proceeds via protonation to give the more stable carbocation intermediate.
Which alkene is more reactive?
1) In acid-base reactions, alkynes are the most reactive followed by alkenes and alkanes. This is due to the stability of conjugate base of alkyne by sp hybridized carbon atom. 2)In electrophilic substitution, alkynes are less reactive than alkenes.
Why is hydrogen iodide more reactive than HCl?
We conceive that the acid protonates the hydroxyl group in step (i), and certainly hydrogen iodide is a STRONGER acid than hydrogen chloride, and hydrogen bromide so that this protonolysis should be more facile, and in step (ii) the halide counter ion acts as a nucleophile, and displaces the water, a good leaving group …
