Leilani · Answer 1

For the tetrahedral case the repulsion is smaller.

Explanation:

It is smaller for the tetrahedral case because he angles for tetrahedral molecules are greater (109.5) then for octahedral molecules (90). The greater the distance between the atoms the smaller the repulsion, and so the bigger are angles the bigger is distance.
