MCQ
Which of the following will not act as oxidising agents?
$a. \text{CrO}_3$
$b. \text{MoO}_3$
$c. \text{MoO}_3$
$d. \text{CrO}_4^{2-}$
  • A
    $a$ and $b$
  • B
    $a$ and $c$
  • $b$ and $c$
  • D
    $a$ and $d$

Answer

Correct option: C.
$b$ and $c$
Higher oxidation states of $W$ and $Mo$ are more stable that is why they will not act as oxidizing agent.
