Question

નીચે આપેલા સંયુગ્મ બેઈઝો ની બેઝિક સામર્થ્ય ઘટતો ક્રમ શું થશે ?

${ }^{-} \mathrm{OH}, \mathrm{R} \overline{\mathrm{O}}, \mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}, \mathrm{C} \overline{1}$

A$\mathrm{C} \overline{1}>\mathrm{OH}>\mathrm{R} \overline{\mathrm{O}}>\mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}$
B$\mathrm{R} \overline{\mathrm{O}}>-\mathrm{OH}>\mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}>\mathrm{C} \overline{1}$
C${ }^{-} \mathrm{OH}>\mathrm{R} \overline{\mathrm{O}}>\mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}>\mathrm{C} \overline{1}$
D$\mathrm{C}_{\overline{1}}>\mathrm{R} \overline{\mathrm{O}}>-{ }^{-} \mathrm{OH}>\mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}$

Solution

b
Strong acid have weak conjugate base Acidic strength :

$\mathrm{H}-\mathrm{Cl}>\mathrm{CH}_3 \mathrm{COOH}>\mathrm{H}_2 \mathrm{O}>\mathrm{R}-\mathrm{OH}$

Conjugate base strength :

$\mathrm{Cl}^{-}<\mathrm{CH}_3 \mathrm{COO}^{-}<\overline{\mathrm{O}} \mathrm{H}<\mathrm{RO}^{-}$
