Question

which of the following molecular geometries exhibits the largest bond angles? planar triangular tetrahedral octahedral trihedral linear

Explanation:

Bond angles depend on molecular geometry: linear has 180°, planar triangular 120°, tetrahedral 109.5°, octahedral 90°/180° (but adjacent bonds are 90°), trihedral is not a standard geometry. Linear has the largest bond angle.

Answer:

linear
