Answer:
None
How does the mechanism of this reaction: R-OH + HCl = R-Cl + H2O?

Alcohols are very poor leaving groups so first it is converted into good leaving group by protonation .
ROH Lone pair on oxygen acts as base and combines with H+ of the acid
ROH + H+ —→ROH2+
H2O is a good leaving group
ROH2+ =====>R + + H2O
R+ is carbocation intermediate and reacts with Cl-
R+ + Cl- ——-> RCl
tertiary and secondary alcohols will favor carbocation mechanism (SN1)
However primary alcohols will favor SN2 mechanism.
Remember stabilty of carbocations
tertiary > secondary > primary
Primary carbocations are not formed as they are less stable and hence reaction adopts SN2 mechanism.
