Question

[Cr(NH3)4(ONO)Cl]NO3 iupac name

Answer 1

Answer:[Co(NH3)4(NO2)Cl]NO3 is called tetraamminechloridonitrito cobalt (III) nitrate

Answer 2

The IUPAC name of $[Cr(NH_{3})_{4}(ONO)Cl]NO_{3}$ is tetraamminechloronitrito chromium (III) nitrate.

Explanation:

• While writing the IUPAC name of the coordination compound the ligands present are arranged in alphabetical order.
• The names of anions present are:

        $NH_{3}$ ⇒ ammine

        Cl ⇒ chloro

        ONO ⇒ nitrito

• Four ammine groups are present so it will written as tetraammine.
• The metal will be named as it is and its O.S (oxidation state) will be written in bracket. In this compound Chromium has +3 O.S so it will written as (III).
• AT last the anion present outside the sphere will be written.
• Therefore, the IUPAC name will be tetraamminechloronitrito chromium (III) nitrate.
