Which of the following is a Lewis acid?

Which of the following is a Lewis acid?

Options

  1. AOH−\mathrm{OH}^{-}
  2. BH+\mathrm{H}^{+}
  3. CF−\mathrm{F}^{-}
  4. DNH3\mathrm{NH}_3

Correct answer

B. H+\mathrm{H}^{+}

Step-by-step solution

OH−,F−\mathrm{OH}^{-}, \mathrm{F}^{-}and NH3\mathrm{NH}_3 are Lewis base because they can donate a lone pair of electrons while H+\mathrm{H}^{+}is a Lewis acid because it can accept a lone pair of electrons.
