Who is the most reducing agent in 15th group hydrides?
The nitrogen hydride is more stable and bismuth hydride is least stable. Due to the least stability of bismuth hydride, it is the strongest reducing agent among all the hydrides of group \[15\] elements.
Why the reducing character of the hydrides increases down the group?
The reducing character increases down the group because ionisation energy decreases as we move down the group from O to Po.
Which is the correct order of reducing character of eh3?
NH3 < PH3 < AsH3 < SbH3 < BiH3.
Why is bih 3 the strongest reducing agent amongst all the hydrides of group 15 elements?
Why is BiH3 the strongest reducing agent amongst all the hydrides of Groups 15 elements? Answer: As we move down the group, the size of the element increases and, therefore, the bond length of the M—H bond increases and its strength decreases.
Which group 15 hydrides has highest bond angle?
ammonia
Among group 15 hydrides, ammonia has the highest bond angle. The small sized nitrogen atom in ammonia has the highest electron density.
Which of the following group 15 hydrides is the strongest reducing agent?
Thus, BiH2 is least stable among the hydrides of group 15 and hence is the strongest reducing agent.
Why bond angle decreases down the group?
The bond angle gradually decreases down the group due to the decrease in bond pair- bond pair repulsions.
Which is the correct order of group 16 elements as per their reducing character?
All hydrides of group 16 elements, except H2O, are reducing agent. The reducing power of these hydrides increase in going from H2S to H2Te, which may be due to increase in the size of the atom and hence decrease in the M-H bond energy.
Which hydrides of group 15 is most basic?
Among group 15 hydrides, ammonia has maximum basic character. This is because a small sized nitrogen atom has the highest electron density.
