Select the correct statements.
ROH behaves as a base.
$C H_{3} O H$ gives Lucas test most quickly
Lesser is the acidic character of alcohol, greater is its reactivity towards Lucas reagent.
Reactivity of $1^{0}, 2^{0}, 3^{0}$ alcohol lies in the following sequence (for Lucas reaction) - $3^{0} > 2^{0} > 1^{0}$

ROH behaves as a base- as it reacts with the acid- HCl-Alcohols are basic in nature- Phenol is not tested by Lucas test as it is acidic-Tertiary alcohols react instantly with Lucas reagent- Secondary alcohol takes some time to react- Primary alcohol does not react with lucas reagent at room temperature- This is because the negative charge of R group is stabilized more by an alpha carbon rather than an hydrogen attached to the carbon-
