Question

The pair of compounds having coordinate covalent bonds is:

• A. $B{r}_2$ and $Hg$
• B. $C{l}_2$ and $F_2$
• C. $N{H}_4^{+}$ and $H_3{O}^{+}$
• D. $Fe$ and $CO$
• E. Diamond and Graphite

Answer 1

The correct option is C $N{H}_4^{+}$ and $H_3{O}^{+}$

$N{H}_4^{+}$ and $H_3{O}^{+}$ have coordinate covalent bonds.
$N{H}_4^{+}$ is formed by a coordinate covalent bond between $N{H}_3$ and $H^{+}$.
$H_3{O}^{+}$ is formed by a coordinate covalent bond between $H_{2}O$ and $H^{+}$.
