पर्याय

• 30

• 27

• 28

• 36

Answer 1

36

Explanation:

[Zn(NH₃)₄]SO₄

EAN = [(atomic number of metal atom − oxidation number of metal atom) + 2 × number of ligands]

[Zn(NH₃)₄]SO₄ can be written as \[\ce{[Zn(NH3)4]^2+ SO^2-_4}\]

EAN = [30 − (+2) + (2 × 4)]

= [28 + 8]

= 36

Thus, EAN of Zn in [Zn(NH₃)₄]SO₄ is 36.
