1.	Ammonia is a good complexing agent. Give reasons. Or Ammonia acts as a ligand. Explain.
Answer» <html><body><p></p>Solution :Due to the presence of a lone pair of electrons on N, `NH_(<a href="https://interviewquestions.tuteehub.com/tag/3-301577" style="font-weight:bold;" target="_blank" title="Click to know more about 3">3</a>)` <a href="https://interviewquestions.tuteehub.com/tag/acts-848461" style="font-weight:bold;" target="_blank" title="Click to know more about ACTS">ACTS</a> as a complexing agent (ligand). As a result, it combines with transition metal cations to formcomplexes. For example : <br/> `underset("Silver chloride")(AgCl)+2NH_(3)tounderset("Diamminesilver (I) chloride")([Ag(NH_(3))_(2)]Cl),underset("Copper <a href="https://interviewquestions.tuteehub.com/tag/sulphate-1234306" style="font-weight:bold;" target="_blank" title="Click to know more about SULPHATE">SULPHATE</a>")(CuSO_(4))+4NH_(3)tounderset("Tetraamminecopper (II) sulphate")([Cu(NH_(3))_(4)]SO_(4)),underset("Chromium chloride")(CrCl_(3))+6NH_(3)tounderset("Hexaamminechromium (<a href="https://interviewquestions.tuteehub.com/tag/iii-497983" style="font-weight:bold;" target="_blank" title="Click to know more about III">III</a>) chloride")([Cr(NH_(3))_(6)]Cl_(3))`</body></html>
