alleryThe coordination number 6 most commonly gives which geometry?
ATetrahedral, with 109.5° angles
BOctahedral, with 90° angles
CSquare planar, with 90° angles
DLinear, with 180° angle
Answer & Solution
Correct answer: B. Octahedral, with 90° angles
CN 6 → octahedral (most common in coordination chemistry).
4 → tetrahedral or square planar.
2 → linear (e.g., Ag(NH3)2⁺).
