Which of the electronic configuration according to crystal field theory of the compound `Rh^(+2)` with `CN=6` is correct when `DeltagtP` ? .

Options

A. `a.(t_(2g)^(6) e_(g)^(1))`
B. `b. (t_(2g)^(5) e_(g)^(2))`
C. `c. (t_(2g)^(5) e_(g)^(1))`
D. `d. (t_(2g)^(3) e_(g)^(3))`

Answer

b

Explanation

`Rh=4d^(5) 5s^(2) ,Rh^(+2) = 4d^(7)`
When `Delta gtP ("Strong field and pairing occurs")` Structure `=4(t_(2g)^(2)e_(g)^(1))` .
