Question

What will be the decreasing order of basic strength of the following conjugate bases? $-\mathrm{OH}, \mathrm{R} \overline{\mathrm{O}}, \mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}, \mathrm{C} \overline{\mathrm{l}}$

Select the correct option:

$\mathrm{C} \overline{\mathrm{1}}>\mathrm{OH}>\mathrm{R} \overline{\mathrm{O}}>\mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}$

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

$-\mathrm{OH}>\mathrm{R} \overline{\mathrm{O}}>\mathrm{CH}_3 \mathrm{CO} \overline{\mathrm{O}}>\mathrm{C} \overline{\mathrm{I}}$

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

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

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