Chemistry - Salt Analysis Question with Solution | TestHub
A salt (X), which produces a golden yellow color flame, reacts with dilute HCl to produce a poisonous gas (G₁) with an odor reminiscent of bitter almonds. Salt (X) also produces another poisonous, odorless gas (G₂) when reacted with concentrated H₂SO₄.
Aq. solution of (X) (excess) produce soluble complex salt [ ] with solution. Aqueous solution of salt produce dark blue coloration with solution.
Bond order in anion of and gas have :-
Options:
Answer:
Solution:
The question is incomplete as the chemical species (X) and (G₂) are not provided. Assuming (X) is nitrate (NO₃⁻) and (G₂) is nitrogen gas (N₂), we can determine their bond orders.
For NO₃⁻: The resonance structures show one double bond and two single bonds, leading to an average bond order of . However, if the question implies a common anion with a bond order of 3, it might refer to a different species or a misunderstanding of "bond order".
For N₂: The Lewis structure shows a triple bond (N≡N), so the bond order is 3.
Given the options, if the correct answer is A (3 and 3 respectively), then (X) must be a species with a bond order of 3. A common anion with a bond order of 3 is cyanide (CN⁻).
Let's assume:
(X) = CN⁻ (cyanide anion)
(G₂) = N₂ (nitrogen gas)
For CN⁻:
The Lewis structure is :C≡N:⁻.
The bond order is 3.
For N₂:
The Lewis structure is :N≡N:.
The bond order is 3.
Therefore, the bond order in CN⁻ is 3 and in N₂ is 3.
The final answer is .
