Question

Treat NO as NO⁺, H₂O as weak-field and NH₃ as strong-field. Let X be the number of electrons in the t 2 g ​ orbitals of [Ru(NO)(NH₃)₅]³⁺, and Y be the number of electrons in the t 2 g ​ orbitals of [Cr(NO)(H₂O)₅]²⁺. Find X − Y.

TestHub · Accepted Answer

In [Ru(NO)(NH₃)₅]³⁺, Ru is +2 (d⁶) and low spin, so t 2 g ​ ⁶, X = 6. In [Cr(NO)(H₂O)₅]²⁺, Cr is +1 (d⁵) and weak-field, so t 2 g ​ ³ e g ​ ², Y = 3. X − Y = 3.
