Which is stronger reducing agent SbH3 or BiH3?

Which is stronger reducing agent SbH3 or BiH3?

Answer. BiH3 is stronger reducing agent than SbH3.It can be explained on the basis of the atomic size. If we move from Sb to Bi, the principle quantum no increases and hence atomic size increases. For this reason Bi-H bond is much more weaker than Sb-H3.

What is meant by reducing agent?

A reducing agent (also called a reductant or reducer) is an element or compound that loses (or “donates”) an electron to an electron recipient (oxidizing agent) in a redox chemical reaction. A reducing agent is thus oxidized when it loses electrons in the redox reaction.

Why is BiH _( 3 the strongest reducing agent amongst all the hydrides of Group 15 elements?

Doen the group (↓) i.e, from N to Bi, the atomic size increases, hence the bond length A-H increases consequently A-H bond strength decreases and tendency to behave as reducing agent increases i.e., BiH3 is the strongest reducing agent amongst all the hydrides of group 15 elements.

Which of the compounds will act as strongest reducing agent?

As the bond dissociation decreases the reducing character of the molecule increases. So, it can be seen that the bond dissociation of stibine is the least and the bond dissociation of ammonia is the most. Hence the stibine will easily donate the proton and will act as the strongest reducing agent.

Which is the strongest oxidizing agent?

fluorine

Which of the following is the strongest reducing agent NH3 PH3 AsH3 SbH3?

NH3 < PH3 < AsH3 < SbH3 < BiH3. therefore BiH3 is the strongest reducing hydride.

Which of the following is the strongest oxidizing agent?

What is the oxidising and reducing agent?

The oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, its oxidation state decreases. The reducing agent is a substance that causes reduction by losing electrons; therefore its oxidation state increases.

Which one is an oxidizing agent?

Common oxidizing agents are oxygen, hydrogen peroxide and the halogens. In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction in which it gains one or more electrons. In that sense, it is one component in an oxidation–reduction (redox) reaction.

Is kmno4 an oxidizing agent?

Potassium permanganate, KMnO4, is a powerful oxidizing agent, and has many uses in organic chemistry.

Is water an oxidizing agent?

In terms of redox, water behaves much as it did in acid-base reactions, where we found it to be amphiprotic. In the presence of a strong electron donor (strong reducing agent), water serves as an oxidizing agent. In the presence of a strong electron acceptor (strong oxidizing agent), water serves as a reducing agent.

Is fe2+ a reducing agent?

Cr2+ is strong reducing agent than Fe2+. Reason: d4 → d5 occurs in case of Cr2+ to Cr3+. But d6 → d5 occurs in case of Fe2+ to Fe3+. In a medium (like water) d3 is more stable as compared to d5.

Which is a stronger reducing agent Cr 2+ or Fe 2+ and why?

Which is a stronger reducing agent Cr2+ or Fe2+ and why? The following reactions are involved when Cr2+ and Fe2+ act as reducing agents. This means that Cr2+ can be easily oxidized to Cr3+, but Fe2+ does not get oxidized to Fe3+ easily. Therefore, Cr2+ is a better reducing agent that Fe3+.

Why Cr2+ is a strong reducing agent?

Cr2+ is a stronger reducing agent because it can lose one of its electron to become Cr3+ in which the t2g level of d-orbital is half filled and eg level is empty.

Which element in 3d series is the strongest reducing agent?

Cr(II) is the strongest reducing agent in the 3d series.

Which element is strong reducing agent in 2 oxidation state and why?

Cr is strongest reducing agent in +2 oxidation state.

Which will act as a reducing agent Cr2+ or mn2+?

Cr2+ is strongly reducing in nature. It has a d4 configuration. While acting as a reducing agent, it gets oxidized to Cr3+ (electronic configuration, d3). This d3 configuration can be written as 3t2g configuration, which is a more stable configuration.

Why is Cr3 more stable than Cr2?

Cr3+ has electronic config. as [Ar] 3d3 i.e.has 3 unpaired electron. According to CFT(Crstall Field Splitting Theory) it has configuration as t2g3and hence is extremely stable in aqueous solution.

Which of the following will act as oxidising agent?

H2O2:Oxygen is present in -1 oxidation state so it can act as both oxidizing as well as reducing agent.

Which acid is also a strong oxidizing agent?

Some acids contain other structures that act as stronger oxidizing agents than hydrogen ions. Generally, they contain oxygen in their anionic structure. These include nitric acid, perchloric acid, chloric acid, chromic acid, and concentrated sulfuric acid, among others.

Which gas is an oxidising as well as reducing agent?

Hydrogen peroxide is considerably stronger as an oxidizing agent than as a reducing agent, especially in acidic solutions.

Which is not oxidizing agent?

Oxygen, con. sulfuric acid and chlorine has the ability to remove electrons form the other atoms. Hydrogen do not have capacity to remove electron form the other atom, there fore it don’t behave as oxidizing agent.
