A) \[[Ag{{(N{{H}_{3}})}_{2}}]Cl\]
B) \[[Ag{{(N{{H}_{3}})}_{2}}]Cl\]
C) \[[Ag(N{{H}_{3}})]Cl\]
D) \[{{[Ag(N{{H}_{4}})]}_{2}}Cl\]
Correct Answer: B
Solution :
It is clear from the chemical formula that Ag is the central metal atom and the ligands are 2 ammonia molecules. Hence, the compound is \[[Ag{{(N{{H}_{3}})}_{2}}]Cl.\] As we know that: \[\text{Boiling}\,\text{point}\,\propto \frac{\text{1}}{\text{Vapour}\,\text{pressure}\,\text{of}\,\text{liquid}}\] Hence, on decreasing vapour pressure, the boiling point increases. Hence, the correct option is (b).
