Question

conjugate base of HF2-​

Answer 1

Explanation:

According to bronsted Lowry theory the base will accept H+ ions and acids will donate H+

So to make parent molecule it's conjugate base just remove 1 H+ so that it can accept 1 H+ and hence base

Same is true for acids .so to make parent molecule it's conjugate acid just add 1 H+ so that it can donate 1 H+ and hence as it's conjugate acid.

For eg

HF.

1.So to make it's conjugate base remove 1 H+ therefore the conjugate base will be F-

2.So to make it's conjugate acid add 1 H+ therefore the conjugate acid will be H2F+

Answer 2

Answer:

H2F2

Explanation:

For a conjugate acid always add an H atom and a positive charge than the base it forms

for a conjugate base remove one H atom and add a negative charge.
