Question

Select the most stable cation
(a) NH₄⁺ (b) CH₅⁺
(c) OH₃⁺ (d) FH₂⁺

Answer 1

Answer:

NH4+ is the most stable cation

Answer 2

NH₄⁺ is the most stable atom.

Explanation:

The stability of the cations depend on the nature of bonds formed between the central atom and peripheral ions.

The bond formed in CH₅⁺ isn't stable at all because of the lack of carbon having extra orbital.

So this cation cannot exist.

FH₂⁺ is the bond between hydrogen ion and fluoride by means of hydrogen bond.

This bond is strong enough, but not as strong as coordinate bond.

OH₃⁺ is the ion that is the hydronium ion.

The bond is a coordinate bond.

NH₄⁺ is the ammonium ion and this is coordinate bond as well.

The ammonium is more stable than oxygen because it achieves the perfect tetrahedral geometry.

Nitrogen also has the vacant orbital where the electrons can roam around, but the oxygen don't have them because of the presence of another lone pair.
