Which alcohol is most reactive towards HCl in the presence of anhydrous ZNCL 2?
Which of the following alcohol is most reactive with HCl in presence of anhydrous Zinc chloride at room temperature ? The reaction with HCl in presence of anhydrous ZnCl2,SN1, substitution. This reaction is fastest in 3∘-alcohols.
Which is maximum reactive toward HCl?
In aqueous solution, the most basic amine is (CH3)2NH and hence it is most reactive towards dilute hydrochloric acid.
Which of the following alcohols is more reactive towards HCl?
So the Benzylic alcohol will be more reactive and it will form benzylic carbocation after removal of water which is resonance stabilized as shown below: so the correct answer is 4.
Which of the following alcohol is most reactive with HCl and anhydrous ZnCl2?
Which of the following compound is most reactive with HCl in presence of anhydrous ZnCl2 (Lucas reagent)? Though benzyl alcohol is a 1º alcohol, it reacts vigorously with Lucas reagent, since benzylic carbocation is very stable.
Which alcohol is least reactive with HCl?
Usually, when treated with HBr or HCl alcohols, they undergo a nucleophilic replacement reaction to create an alkyl halide and water. In ethanol, HCl should be extremely soluble – almost as soluble as it is in water.
Which one of the following is more reactive than the rest towards the mixture of anhydrous zncl2 and HCl?
From amongst the following alcohols the one that would react fastest with conc . HCl and anhydrous ZnCl2, is. 1-Butanol.
Which is least reactive towards HCl?
The least reactive alkene towards dilute hcl is Ethene.
Which compound is the most reactive in acid catalysed dehydration?
So, option A is the most reactive towards the acid-catalysed dehydration.
Which alkane is most reactive in its reaction with HCl?
The most reactive alkene toward hydrochloric acid is Ethene. The order of reactivity of akene depends on the presence of double bonds between carbon-carbon atoms.
Which of the following is the most reactive alcohol?
For the breaking of –O-H bond primary alcohol is most reactive.
Which alcohol is more reactive towards Lucas reagent?
Tertiary alcohols give turbidity immediately with Lucas reagent.
Which is more reactive towards Lucas reagent?
B. Lesser is the acidic character of alcohol, greater is its reactivity towards Lucas reagent. … This reagent is used to distinguish between, primary, secondary and tertiary alcohols.
