The best method to prepare cyclohexene from cyclochexanol is by using

A

Conc.`HCI+ZnCI_(2)`

B

Conc.`H_(3)PO_(4)`

C

`HBr`

D

Conc.`HCI`

Text Solution

Verified by Experts

The correct Answer is:
B
Conc. `HCI, HBr` and conc. `HCI +ZnCI_(2)` all are nucleophiles thus convert alcohols to alky`1` halides. However, conc. `H_(3)PO_(4)` is a good dehydrating agent which converts and alcohol to an alkene.
