323094 Which of the following compounds will most readily be dehydrated to give alkene under acidic condition?

323095 Ethanol is converted into ethoxyethane

323096 Which of the following statements are correct regarding dehydration of alcohols?
I. Conc. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) or conc. \(\mathrm{H}_{3} \mathrm{PO}_{4}\) or anhyd. \(\mathrm{ZnCl}_{2}\) or \(\mathrm{Al}_{2} \mathrm{O}_{3}\) can be used as dehydrating agent for alcohol.
II. The mechanism involves: Protonation \(\rightarrow\) Formation of carbocation \(\rightarrow\) Deprotonation
III. Primary alcohols are the easiest to dehydrate.
IV. Formation of carbocation is the rate determining step.

323097 Read Assertion and Reason carefully to mark the correct option given below.
Assertion :
Alcohols do not react with NaBr but when \(\mathrm{H}_{2} \mathrm{SO}_{4}\) is added they form alkyl bromides.
Reason :
Protonation of the – OH group by \(\mathrm{H}_{2} \mathrm{SO}_{4}\) convert it into the \(-\stackrel{\oplus}{\mathrm{O}} \mathrm{H}_{2}\) group which has a better-leaving tendency.
