WebJun 18, 2024 · Why is BiH 3 the strongest reducing agent amongst all the hydrides of Group 15 elements? Answer: This is because as we move down the group, the size increases, as a result, length of E-H bond increases and its strength decreases, so that the bond can be broken easily to release H 2 gas. Hence, BiH 3 is the strongest reducing agent. Question 3. WebReducing agent. In chemistry, a reducing agent (also known as a reductant, reducer, or electron donor) is a chemical species that "donates" an electron to an electron recipient (called the oxidizing agent, oxidant, oxidizer, or electron acceptor ). Examples of substances that are common reducing agents include the alkali metals, formic acid ...

On … WebCorrect option is B) Among the elements of alkaline earth metals, barium is the strongest reducing agent. On moving down the group, the atomic size increases. The electropositive character increases and the ionization enthalpy value decreases. Hence, reducing power also increases from Be to Ba. Hence, option B is correct.
WebWhy is BiH 3 the strongest reducing agent amongst all the hydrides of group 15 element? Solution: Because BiH 3 is the least stable among the hydrides of group 15. Question 3. Why is N 2 less reactive at room temperature? Solution: Because of strong pπ – pπ overlap resulting into the triple bond.
