    Alcohols may behave as:

    Alcohols are neutral as they do not influence the pH. Due to — bond, they possess Bronsted acid nature showing cleavage of — bond. Also due to the presence of lone pair of electron on oxygen atom, they act as Lewis base. The reactivity order is based on  of alkyl groups.
    Lewis base order : 3 space ͦ greater than 2 space ͦ greater than 1 space ͦ Bronsted acid order : 1 space ͦ greater than 2 space ͦ greater than 3 space ͦ
