Out of 2-chloroethanol and ethanol which is more acidic and why?

Explanation

2-chloroethanol is more acidic than ethanol. Due to -I-effect (electron withdrawing group) of the Cl-atom, electron density in O-H bond decreases. So, O-H bond of 2-chloroethanol becomes weaker than O-H bond of ethanol and thus, the release of `H^(+)` ion from O-H bond of 2-chloroethane becomes easier. Thus, 2-chloroethanol is more acidic than ethanol.
