Construct a three-step synthesis of 1,2-epoxycyclopentane from cyclopentanol by dragging the appropriate formulas into the bins.
Note that each bin will hold only one item, and not all of the given reagents or structures will be used.

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
- 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
- Full reaction scheme has been shown below

Answer : It take time for the concentration to become 0.180 mol/L will be, 277.8 s
Explanation :
The integrated rate law equation for second order reaction follows:
where,
k = rate constant =
t = time taken = ?
[A] = concentration of substance after time 't' = 0.180 mol/L
= Initial concentration = 0.360 mol/L
Putting values in above equation, we get:
Hence, it take time for the concentration to become 0.180 mol/L will be, 277.8 s
