The acidity of alcohol,phenol,and carboxylic acid differs. Demonstrate their reactivity with $Na$,$NaOH$,and $NaHCO_3$ using the table below.
Compound Reaction with $Na$ metal Reaction with $NaOH$ Reaction with $NaHCO_3$
Alcohol $H_2$ is liberated No reaction No reaction
Phenol $H_2$ is liberated Soluble salt formed No reaction
Carboxylic acid $H_2$ is liberated Soluble salt formed $CO_2$ gas is liberated

(N/A) The acidity of these compounds follows the order: $Carboxylic \ acid > Phenol > Alcohol$.
$1$. $Na$ metal: All three compounds contain an acidic hydrogen atom ($-OH$ group),so they all react with $Na$ to liberate $H_2$ gas.
$2$. $NaOH$: Carboxylic acids and phenols are acidic enough to react with the strong base $NaOH$ to form water-soluble salts. Alcohols are too weakly acidic to react with $NaOH$.
$3$. $NaHCO_3$: Only carboxylic acids are strong enough to react with the weak base $NaHCO_3$ to liberate $CO_2$ gas. Phenols and alcohols are not acidic enough to decompose $NaHCO_3$.
