Which of the following does not contain any coordinate bond?
Which of the following does not contain any coordinate bond?
Options
- A(\mathrm{H}_3 \mathrm{O}^{+})
- B(\mathrm{BF}_4^{-})
- C(\mathrm{HF}_2^{-})
- D(\mathrm{NH}_4^{+})
Correct answer
C. (\mathrm{HF}_2^{-})
Step-by-step solution
Only (\mathrm{HF}_2^{-})has (\mathrm{H})-bonding ([\mathrm{F}-\mathrm{H} \ldots . . \mathrm{F}]^{-})rest all the molecules have coordinate bonds.
