Q47 / 180 · AIIMS 2004 · Chemistry

Among the following the dissociation constant is highest for

  • A
    $\mathrm{C}_6 \mathrm{H}_5 \mathrm{OH}$
  • B
    $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{OH}$
  • C
    $\mathrm{CH}_3 \mathrm{C} \equiv \mathrm{CH}$
  • Correct answer
    D
    $\mathrm{CH}_3 \mathrm{NH}_3^{+} \mathrm{Cl}^{-}$

Solution

$\mathrm{CH}_3 \stackrel{+}{\mathrm{NH}_3} \mathrm{Cl}$ is a salt which can be completely ionized in aqueous solution.

Hence, the correct answer is option: 'D'.
