Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Complete hydrolysis of ${\mathrm{TeF}}_6$ produces telluric acid (${\mathrm{H}}_6{\mathrm{TeO}}_6$) and hydrofluoric acid ($\mathrm{HF}$), which are two distinct types of acids.

The reaction is:

$${\mathrm{TeF}}_6+6{\mathrm{H}}_2\mathrm{O}\to {\mathrm{H}}_6{\mathrm{TeO}}_6+6\mathrm{HF}$$

Let's analyze the other options:

A. ${\mathrm{XeF}}_6$ on complete hydrolysis produces perxenic acid (${\mathrm{H}}_4{\mathrm{XeO}}_6$) and hydrofluoric acid ($\mathrm{HF}$). This also produces two types of acids. However, tellurium is a better example for this type of question as it is a p-block element, and its hydrolysis behavior is often compared with other group 16 elements.

B. ${\mathrm{NCl}}_3$ on complete hydrolysis produces ammonia (${\mathrm{NH}}_3$) and hypochlorous acid ($\mathrm{HOCl}$). Ammonia is a base, not an acid.

D. ${\mathrm{BiCl}}_3$ on complete hydrolysis produces bismuth oxychloride ($\mathrm{BiOCl}$) and hydrochloric acid ($\mathrm{HCl}$). Bismuth oxychloride is a salt, not an acid.

Therefore, ${\mathrm{TeF}}_6$ is the best answer among the given options that produces two types of acids on complete hydrolysis.
