Hydronium ion.

Draw an electron dot diagram of hydronium ion. State the type of bonding present in it.

Answer 1

\[\begin{array}{cc}
\phantom{..}\ce{\underset{\bullet\bullet}{\mathbf{H}}}\\
\ce{\mathbf{H}\phantom{.}}^{\bullet}_{\bullet}\phantom{.}\mathbf{O^+}^{\bullet}_{\bullet}\\
\phantom{...}\ce{\overset{\bullet\bullet}{\ce{\mathbf{H}}}}\
\end{array}\]

It has coordinate (dative covalent) bonding.
