MCQ
$IUPAC$ name of $Na_3[Co(ONO)_6]$ is
- ✓Sodium cobalt nitrite
- BSodium hexanitrito $-O-$ cobaltate $(III)$
- CSodium hexanitrocobalt $(III)$
- DSodium hexanitrito cabaltate $(II)$
✓
Answer
Correct option: A.
Sodium cobalt nitrite
a
$CrO_2Cl_2$
Let $O$. No. of $Cr\, = x$
$\therefore $ $x +2 (-2) +2 (-1 )\,=0$
$CrO_2Cl_2$
Let $O$. No. of $Cr\, = x$
$\therefore $ $x +2 (-2) +2 (-1 )\,=0$
$x - 4 - 2\,=0$
$\therefore $ $x\, = +6$
