Question
Assertion(A) :- Geometrical isomerism cannot be shown by tetrahedral complexes.Reason(R) :- All four ligands in tetrahedral geometry have adjacent position to one another and all four bond angles are the same (=109.5°)
Solution
The assertion (A) and the reason (R) are both correct and the reason (R) is the correct explanation for the assertion (A).
Geometrical isomerism is a form of stereoisomerism that arises due to the difference in the spatial arrangement of ligands. In tetrahedral complexes, the four ligands are arranged in such a way that they are all adjacent to each other and have the same bond angles (109.5°). This means that there is no possibility of arranging the ligands differently to form different geometrical isomers. Therefore, tetrahedral complexes cannot show geometrical isomerism.
