Q22 / 180 · KCET 2019 · Chemistry

Which of the following is least soluble in water at \( 298 \mathrm{~K} ? \)

  • A
    \( \left(\mathrm{CH}_{3}\right)_{2} \mathrm{NH} \)
  • B
    \( \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{NH}_{2} \)
  • C
    \( \mathrm{CH}_{3} \mathrm{NH}_{2} \)
  • Correct answer
    D
    \( \left(\mathrm{CH}_{3}\right)_{3} \mathrm{~N} \)

Solution

(D)
"D" is least soluble as there is no scope of H-bonding.

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