Question

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

109.5
107
105
120.0
117
180

Explanation:

In chemistry (a subfield of Natural Science), trigonal pyramidal molecules (like NH₃) have a bond angle of approximately 107 degrees due to the lone pair - bond pair repulsion which compresses the ideal tetrahedral angle (109.5°) to around 107°.

Answer:

B. 107 (assuming the second option is labeled as B, with the text "107")
