Answer:
90°
Step-by-step explanation:
A molecule with an octahedral shape has a central atom bonded by six atoms or groups of atoms with no lone pairs of electron. The ideal bond angles is 90°. Examples of compounds with octahedral shape are sulfur hexafluoride SF₆ and molybdenum hexacarbonyl Mo(CO)₆
For a molecule with an octahedral shape:
Number of Electron Groups = 6
Electron-Group Geometry = octahedral
Number of Lone Pairs = 0
Valence Shell Electron Pair Repulsion (VSEPR) Notation = AX₆E₀ or AX₆
Ideal Bond Angles = 90°
