Question

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

109.5
107
105
120.0
117
180

Explanation:

In molecular geometry, a linear molecule has atoms arranged in a straight line. The bond angle for a linear molecular geometry (e.g., in molecules like \(CO_2\)) is \(180^\circ\) because the atoms lie on a straight line, forming a straight - angle. The other options (\(109.5^\circ\) is for tetrahedral, \(107^\circ\) for trigonal pyramidal, \(105^\circ\) for bent (water - like), \(120^\circ\) for trigonal planar) do not correspond to linear molecules.

Answer:

180 (the option with "180")
