Why does reducing property of dioxide decreases down the group?
The dioxide molecules contain pπ–pπ bonds which become weaker with increase in atomic number because, increase in atomic no. increases size along a group and hence there occurs an increase in the bond length and so the reducing character decreases down the group.
Why does the reducing property of dioxide decreases from SO2 to teo2?
As the size of group 16 elements increases down the group, the element–oxygen bond strength decreases from SO2 to TeO2. Therefore, the bond dissociation enthalpy decreases. Hence, due to increase in the tendency to release oxygen, the oxidising tendency increases and, consequently, the reducing character decreases.
Why does reducing property increase down the group?
The reducing property depends on the ionisation potential and electron affinity of the elements. Hence, the tendency to lose electrons increases, and thus, the reducing property also increases along the group from top to bottom.
Why does reducing character decreases down the group?
This is due to a decrease in their bond dissociation enthalpy. Reducing character is directly related to the ease of losing hydrogen. Stability decreases down the group as the bond dissociation energy decreases. Hence, the bond dissociation energy decreases down the group due to the increase in the central atom size.
Why does oxidising power increases down the group 16?
Answer: As we move from left to right, the electronegativity of elements increases, so they have less tendency to lose electrons and non-metallic character of elements increases. So as the non-metallic character increases so oxidizing power of elements increases from left to right along a period.
How does the reducing property vary in the periodic table?
Oxidising character decreases and reducing character increases down the group.
Is SO2 oxidizing or reducing agent?
Featuring sulfur in the +4 oxidation state, sulfur dioxide is a reducing agent.
Why does reducing character increases down the group 15?
The reducing character of hydrides of group 15 elements increases from top to bottom because the E-H strength (Here E= N, P, As, Sb, or Br) bond decreases down the group due to an increase in the size of the central atom.
Why does reducing character of group 15 increase down the group?
The reducing character increases down the group because the bond strength of the E−H bond decreases. As the size of the element E down the group increases and thus the bond dissociation energy decreases. This facilitates the dissociation of Hydrogen atoms and hence down the group, thus the reducing character increases.
Why does reducing character increase down group 15?
As we move down in group 15 the size of the group 15 element increases which causes the length of the bond between the hydrogen atom and the group 15 element to increase. This in turn decreases the strength of the bond between hydrogen atom and the group 15 element, hence making it easier to donate a hydrogen atom.
How does the reducing property of oxides change down a group?
Therefore, as we move from top to bottom in the group, lower oxidation state becomes more stable. Thus, the tendency of element to attain higher oxidation state decreases. Hence, the reducing property of oxides of group 13, 14, 15, 16 decreases down a group. In Group 15, elements show (+3) and (+5) oxidation states.
What is the reducing character of hydrides of Group 15 elements?
The reducing character of hydrides of group 15 elements increases from top to bottom because the E-H strength (Here E= N, P, As, Sb, or Br) bond decreases down the group due to an increase in the size of the central atom. The stability of hydrides decreases down the group from NH 3 to BiH 3.
What is meant by reducing property of a compound?
Reducing property means the ability of the compound to reduce the other. more reducing property means it will easily lose the electrons….. we know down a group atomic size increases and therefore, the ionization potential (IP orI E) decreases.
Why is sulphur dioxide a reducing agent?
Sulphur dioxide is reducing agent because sulphur has d orbital so it can easily expand its oxidation state +4 to +6 and thus behave as reducing agent. in the case of TeO2, Te is a heavier element and due to inert pair effect, the Te does expand its oxidation state +4 to +6.
