Question

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

109.5
107
105
120.0
117
180

Explanation:

In chemistry (a subfield of Natural Science), the bond angle in a tetrahedral molecular geometry (where a central atom is bonded to four other atoms with no lone pairs) is known to be approximately \(109.5^\circ\). The other options correspond to different geometries: \(107^\circ\) is for trigonal pyramidal (with one lone pair), \(105^\circ\) for bent (two lone pairs), \(120^\circ\) for trigonal planar, \(117^\circ\) is not a standard tetrahedral angle, and \(180^\circ\) for linear.

Answer:

A. 109.5
