Which of the following does not contain any coordinate bond?

  • A
    $\mathrm{H}_{3} \mathrm{O}^{+}$
  • B
    $\mathrm{BF}_{4}{ }^{-}$
  • Correct answer
    C
    $\mathrm{HF}_{2}{ }^{-}$
  • D
    $\mathrm{SO}_{2}{ }^{-}$

Solution

$\mathrm{HF}_{2}$ is the only compound among the given options which does not contain any coordinate bond because it has hydrogen bonding. $[\mathrm{H}-\mathrm{F} \bullet \bullet \bullet \mathrm{H}]^{-}$

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