Question

Although carbon and hydrogen are better reducing agents but they are not used to reduce metallic oxides at high temperatures.why? q23. why do tetrahedral complexes not show geometrical isomerism?

Answer 1

a) Carbon and hydrogen are better reducing agents.

However at high temperatures carbon combine with metals to form metal carbides and with hydrogen to form metal hydrides.

b) Tetrahedral compounds do not show geometrical isomerism because the relative position of unidentate ligand attached to the central atom are same with respect to each other.

Answer 2

Explanation:

Carbon forms carbides and hydrogen form hydrides and not pure metals

All ligands are at equal distance from the central metal atom.
