MCQ
Which of the following molecules does not have co- ordinate bonds?
- A$PH^+_4$
- B$NO_2$
- C$O_3$
- ✓$CO^{2-}_3$
Methyl isocyanide, carbon monoxide, and ozone contain coordinate bonds. In Methyl isocyanide, the dative bond is present between $N$ and $C$ of isocyanide ion.
In $CO$, the dative bond is present between $C$ and $O$. In $O _3$, the dative bond is present between $2$ oxygen atoms.

$Fe ^{2+}( aq )+ S ^{2-}( aq ) \rightleftharpoons FeS ( s )$
When equal volumes of $0.06 M Fe ^{2+}( aq )$ and $0.2 M S ^{2-}( aq )$ solutions are mixed, the equilibrium concentration of $Fe ^{2+}$ (aq) is found to be $Y \times 10^{-17} M$. The value of $Y$ is. . . . .
