Which of the following statement is correct for complex [Cr(NH_(3))(CN)_(4)(NO)^(2-)] (given that n=1) ?

Answer»

It is `d^(2)sp^(3)` hybridized.
The chromium is in `+1` oxidation state.
It is heteroleptic complex and its AQUEOUS SOLUTION is colourd .
All of these

Solution :`[overset(+1)(CR)(Noverset(0)(H)_(3))(Coverset(-4)(N))_(4) (Noverset(+1)(O))]^(2-),d^(2)sp^(3) , (t_(2g)^(2 , 2, 1) eg^(0,0))`
