MCQ
In ozone molecule, the formal charge on the central oxygen atom is
  • A
    $-1$
  • B
    $2$
  • C
    $0$
  • $1$

Answer

Correct option: D.
$1$
$=\left[\begin{array}{l}\text { Total no. of } \\ \text { valence dectrons } \\ \text { in the free atom }\end{array}\right]-\left[\begin{array}{l}\text { Total no. of } \\ \text { non-bonding } \\ \text { electrons }\end{array}\right]-\frac{1}{2}\left[\begin{array}{l}\text { Total no. } \\ \text { of bonding } \\ \text { electrons }\end{array}\right]$
The formal charge on the central oxygen atom
$=6-2-(1 / 2) \times 6$
$=+1$
