1.	Identify the correct naming for [Co(ONO)(NH3)5]^2+.(a) Pentaamminenitritocolbalt(III)(b) Pentaamminenitrito-O-cobalt(III)(c) Pentaamminenitrito-N-cobalt(III)(d) Pentaamminenitrosylcobalt(III)This question was posed to me by my college director while I was bunking the class.My query is from Nomenclature of Coordination Compounds topic in division Coordination Compounds of Chemistry – Class 12
Answer» Correct ANSWER is (b) Pentaamminenitrito-O-cobalt(III) The explanation is: Nitrate is an ambidentate ligand and can BIND through either O or N ATOM. In this case, it is written as (ONO) which implies that it binds through O atom, hence giving it the NAME nitrito-O.
