MCQ
Which has a coordinate bond
  • ✓
    $SO_3^{2 - }$
  • B
    $C{H_4}$
  • C
    $C{O_2}$
  • D
    $N{H_3}$
✓

Answer

Correct option: A.
$SO_3^{2 - }$
(a) $S{O_3}^{2 - }$ has one coordinate bond.

$\begin{array}{*{20}{c}}
  {{O^ - } \leftarrow S \to {O^ - }} \\ 
  { \downarrow {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} } \\ 
  {O{\mkern 1mu} {\mkern 1mu} } 
\end{array}$
