Construct a three-step synthesis of 1,2-epoxycyclopentane from cyclopentanol by dragging the appropriate formulas into the bins.

vladimir2022 [97]

Answer:

(1) Bromination, (2) E2 elimination and (3) epoxidation

Explanation:

In the first step, -OH group in cyclopentanol is replaced by more facile leaving group Br by treating cyclopentanol with $PBr_{3}$

In the second step, E2 elimination in presence of strong base e.g. NaOEt/EtOH produce cyclopentene

In the third step, treatment of cyclopentene with mCPBA produces 1,2-epoxycyclopentane
