Question

Regarding the oxidation states of elements of transition element the incorrect statement is

• A. $M{o}^{+6}$ is more stable than $C{r}^{+6}$
• B. $W^{+6}$ is more stable than $C{r}^{+6}$
• C. Oxyanion of $C{r}^{+6}$ in acidic medium is better oxidizing agent than oxides of $Mo$ and $W$ in $+6$ oxidation state.
• D. Higher oxidation states are shown by metals when they are attached to $\pi$ - acceptor ligands.

Answer 1

Answer: (D)

Lower oxidation states are shown by metals when they are attached to $\pi$ - acceptors ligands.
