Which of the following alcohol will be most reactive towards anhydrous ZnCl2?
Hence, tertiary butyl alcohol is most reactive with Lucas Reagent.
Which alcohols are the most reactive?
Tertiary alcohols are more reactive because the increased number of alkyl groups increases +I effect. So, the charge density on carbon atom increases and hence around oxygen atom.
Which of the following compound is most reactive with in presence of anhydrous Lucas reagent?
Though benzyl alcohol is a 1º alcohol, it reacts vigorously with Lucas reagent, since benzylic carbocation is very stable.
Which alcohol is most reactive towards Na?
Explanation: Methyl alcohol is also VERY reactive towards sodium metal. Ethyl alcohol reacts more slowly, but is still zippy. Above ethyl alcohol, propyl alcohol and butyl alcohol are very sluggish; and will likely not fully react without heating.
Which alcohol is most reactive towards HCl in the presence of anhydrous ZnCl2 a primary B secondary C tertiary D all of these?
Tertiary alcohols are more reactive towards halogen acids than secondary alcohols.
Which is more reactive towards electrophilic substitution?
The compound which is most reactive towards the electrophilic substitution is the Methyl group. Activating groups attached to the benzene ring increase the reactivity of benzene towards electrophilic substitution.
Why tertiary alcohol is most reactive?
The tertiary alcohol is more reactive than other alcohols because of the presence of the increased number of alkyl groups. These alkyl group increases the +I effect in the alcohol.
Which alcohol is most stable?
The tertiary carbocation formed during dehydration of 2-methyl-2-propanol is most stable.
Why are alcohols reactive?
The functional group of the alcohols is the hydroxyl group, –OH. Consequently, the covalent bonds of this functional group are polarized so that oxygen is electron rich and both carbon and hydrogen are electrophilic. …
Which alcohol is more reactive towards Lucas reagent?
Primary, Secondary, and Tertiary alcohols react with the lucas reagent to form the chloroalkane at different rates. Tertiary alcohols react the fastest due to the fact the organic chloride has relatively low solubility in the aqueous mixture.
Which is more reactive towards Lucas reagent?
Lesser is the acidic character of alcohol, greater is its reactivity towards Lucas reagent- this is true, as bases react with Lucas reagent, but acidic compounds do not react with this reagent. For example phenol does not react with Lucas reagent due to its high acidity.
Which of the following alcohols is most reactive towards acetic acid?
Formed during esterification become more and more crowded and hence the rate of esterification decreases accordingly. Thus, the smallest alcohol i.e. CH3OH reacts at the fastest rate.
Which HBr is most reactive?
Among HI, HBr and HCl, HI is most reactive towards alcohols.
Are primary alcohols more reactive than secondary alcohols?
Explanation: Tertiary alcohols have greater reactivity with hydrogen halides than secondary alcohols — which in turn have greater reactivity than primary alcohols — in reactions forming alkyl halides. For tertiary alcohols, the reaction proceeds by an S N1 mechanism which prefers a more substituted alcohol.
Which of the following alcohols is most reactive towards carboxylic acid?
Answer: CH3CH2COOH is most reactive towards esterification as C atom of carboxylic group is stericaly least hindered.
