Alcohols are acidic in nature because hydrogen is attached to oxygen which is an electronegative element. Alcohol is weaker acid than water because `OH^(-)` ion is more stable than `R-O^(-)` ion. `R-O^(-)` is less stable, due to `+I` effect of the alkyl group. Acidity of alcohols increases with increase in the stability of acid anion.

Some alcohol like `CH_(3)-OH, CF_(3)-CH_(2)-OH, (CF_(3))_(3)C-OH` ae more acidic than water.
Lucas test of alcohols involves following reaction `:`
`R-OH+underset("conc.")(HCl)underset(ZnCl_(2))overset("anhydrous")(rarr)underset("white turbidity")(RCl)+H_(2)O`
Select the correct statements for the Lucas test.

A

ROH behaves as a base

B

Lesser is the acidic character of alcohol, greater is its reactivity towards Lucas reagent.

C

Reactivity of `1^(@),3^(@),3^(@)` alcohol, lies in the following sequence (for Lucas reaction ) `3^(@) gt 2^(@) 1^(@)`

D

`CH_(3)OH` gives Lucas test most quickly .
