Question

1. what is the bond angle of a trigonal planar molecule? (1 point) *

109.5
107
105
120.0
117
180

Explanation:

In chemistry (a subfield of Natural Science), a trigonal planar molecular geometry has a bond angle of 120.0 degrees. This is because the three bonding regions are arranged symmetrically in a plane around the central atom, leading to equal angles between each bond. The other options (109.5, 107, 105, 117, 180) correspond to different molecular geometries (e.g., tetrahedral, trigonal pyramidal, bent, linear).

Answer:

D. 120.0 (assuming the options are labeled A to F with D being 120.0; if the original options have different labels, adjust accordingly. Based on the given list, the option with 120.0 is the correct one for the bond angle of a trigonal planar molecule.)
