Question

Consider following compounds:
$I:K_4\left[Fe\right(CN{)}_6],II:N{H}_{4}Cl,III:H_{2}S{O}_4$
Ionic, covalent and coordinate bonds are present in.

• A. I, II and III
• B. I and III
• C. II and III
• D. I and II

Answer 1

The correct option is D I and II

$I:K_4\left[Fe\right(CN{)}_6]$: Ionic bonds between $K$ and$\left[Fe\right(CN{)}_6]$, covalent bonds between $C$ and $N$, coordinate bonds between $Fe$ and $CN$.

$II$: $N{H}_{4}Cl$: Ionic bonds between $N{H}_4^{+}$ and $Cl$, covalent bonds between $N$ and $H$, coordinate bonds between $N{H}_3$ and $H^{+}$.

$III$: $H_{2}S{O}_4$: Ionic bonds between $H$ and $S{O}_4^{-2}$, covalent bonds between $S$ and $4O$ atoms.
