CBSE Class 12 · 2001 · Delhi · Coordination CompoundsVery Short Answer

Write the IUPAC name for any one of the isomers of [Cr(NH

_{3}

)

_{4}

_{2}

]

^{+}

Answer: cis-Tetraamminedichloridochromium(III) ion (or the trans- isomer).

Solution

[Cr(NH

_{3}

)

_{4}

_{2}

]

^{+}

is octahedral of type MA

_{4}

_{2}

— it exists as cis and trans geometrical isomers.
Name either: \textit{cis}-tetraamminedichloridochromium(III) ion or \textit{trans}-tetraamminedichloridochromium(III) ion.
