Ethanol when reacted with \(\mathrm{PCl}_{5}\) gave \(\mathrm{A}, \mathrm{POCl}_{3}\) and \(\mathrm{HCl}\). A reacts with silver nitrate to form \(\mathrm{B}\) (major product) and \(\mathrm{AgCl}\). A and \(\mathrm{B}\) are respectively
Tertiary alcohol readily reacts with halogen acid. Presence of three alkyl groups increases electron density on \(3^{\circ}\) carbon atom. Hence, \(-\mathrm{OH}\) group is easily removed. After removal of - \(\mathrm{OH}\) group, \(3^{\circ}\) carbonium ion is formed which is most stable.

Which reagent would be best for the conversion of tert-butanol into tert-butyl bromide?
1 \(\mathrm{PBr}_{3}\)
2 \(\mathrm{HBr}\)
3 \(\mathrm{NaBr}\)
4 \(\mathrm{Br}_{2}, \mathrm{NaOH}\)
Explanation:
Without rearrangement reaction takes place only in the presence of \(\mathrm{PBr} 3\). In presence of \(\mathrm{HBr}\), rearrangement takes place.
