Question

Which of the following is the strongest base? A) CI B) CIO4 C) F D) NO3 E) H20

Answer 1

Answer: Option (C) is the correct answer.

Step-by-step explanation:

It is known that a weak acid upon dissociation will lead to the formation of a strong conjugate base. Whereas if an acid is strong then it will lead to the formation of a weak conjugate base.

For example, HF is a weak acid and when it will dissociate then it will give hydrogen ion and fluroide ion.

The reaction will be as follows.

`HF \rightarrow H^(+) + F^(-)`

Here,
`F^(-)` is the conjugate base and
`H^(+)` is the conjugate acid.

Whereas HCl is a strong acid and its
`Cl^(-)` will be a weak conjugate base. Similarly,
`ClO^(-)_(4)` and
`NO^(-)_(3)` are also weak base.

Thus, we can conclude that out of the given options
`F^(-)` is the strongest base.
