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