Question

Select the correct I.U.P.A.C name for $\left[Cr{\left(N{H}_3\right)}_{3}C{l}_3\right]$ complex :

• A. Triamminetrichloridochromate$\left(III\right)$
• B. Triamminetrichloridochromium$\left(III\right)$
• C. Trichloridotriamminechromium$\left(III\right)$
• D. Trichloridotriamminechromate$\left(III\right)$

Answer 1

The correct option is B Triamminetrichloridochromium$\left(III\right)$

Option (B) is correct.
I.U.P.A.C name for $\left[Cr{\left(N{H}_3\right)}_{3}C{l}_3\right]$ complex is triamminetrichloridochromium$\left(III\right)$

In the complex,ammine is named first followed by chlorido (-ve charge so ends with 'o')and chromium has +3 oxidation state.
