The alcohol that is dehydrated most easily with conc. H2SO4 is p−CH3OC6H4CH(OH)CH3.
Which of the following undergoes dehydration easily?
Primary alcohols are dehydrated easily than secondary and teritary alcohols.
Which alcohol can be easily dehydrated?
Tertiary alcohols tend to be easier to dehydrate and primary alcohols to be the hardest.
Which of the following alcohols undergoes dehydration most readily?
Which of the following would most readily undergo dehydration? In general, the bulkier the alcohol, the faster the rate of dehydration will be. The rate of dehydration of alcohols follows the order: 3° > 2° > 1°. Thus, [D], which is a tertiary alcohol, will undergo dehydration the fastest.
Which of the following is the correct ease of dehydration?
I > II > III. III > II > I. I > III > II.
Which of the following alcohol will have the fastest rate of dehydration?
Hence, alcohol given in option C will have the fastest rate of dehydration.
Which of the following alcohols produce the most stable carbocation?
Thus most stable carbocation is formed by 2-Methyl -2- propanol during its dehydration.
Which of the following alcohols gives 2 Butenc on dehydration by conc H2SO4?
Answer. 2-butene can be obtained by dehydration of Butane-2-ol by using concentrated H SO . Hence , the option (c) is the correct answer . Concentrated H SO is used as a dehydrating agent to obtain alkene from alcohols of alkane .
Does phenol undergo dehydration?
Phenol (I) is stable aromatic compound. So it is most stable. The diene (IV) undergoes quick dehydration because it will form stable phenol.
Which of the following alcohols will dehydrate most rapidly when treated with h2 S o4?
Alcohols will dehydrate most rapidly when treated with conc. H2SO4.
What is the order of dehydration of primary secondary and tertiary alcohols?
The order of the ease of dehydration of alcohols is: tertiary > secondary > primary. Secondary and tertiary alcohols are best dehydrated by dilute sulfuric acid.
Which one of the following alcohols is least soluble in water?
Of the given options, the largest alcohol of all is 1- pentanol and will thus have the least solubility in water.
What is catalytic dehydrogenation of alcohols?
On catalytic dehydrogenation, primary alcohols give aldehydes, secondary alcohols give ketones and tertiary alcohols give alkene. Primary and secondary alcohols show a type of beta-elimination in which −OH group from alfa and hydrogen from beta carbon.
