Question

Give reason H2Te is the strongest reducing agent amongst all the hydrides of Group 16 elements.

Answer 1

H2Te is the strongest reducing agent of group 16 elements because, due to the large size of Te the inter molecular forces are weak.So it can lose electrons simply i.e.,it can undergoes oxidation simply.

Answer 2

$H_2Te$ is the strongest reducing agent among the halides of group 16 elements.

Explanation:

• The elements present in group 16 are Oxygen, Sulphur, Selenium, Tellurium and Polonium.
• Hydrides of all elements of group 16 except oxygen are reducing agent. As hydride of oxygen is water it is not considered a reducing agent.

• The reducing character of group 16 hydrides increases from $H_2S$ to $H_2Te$.
• As we move from $H_2S$ to $H_2Te$, the thermal stability decreases, due to which the reducing character of the elements increases.
• Due to this reason, $H_2Te$ is considered as the strongest reducing agent amongst all the hydrides of group 16 elements.
