Geometrically tetrahedral means that the electron groups have what angle? a. 120° b. 180° c. 90° d. 109.5°

109.5° (d)

Explanation:

Use the table 10.1 to determine the

1. Electron geometry

2. Molecular geometry

3. Bond angles

-Four electron groups give a tetrahedral electron geometry

- two bonding groups and two lone pair give a bent molecular geometry

- the idealized bond angles for tetrahedral geometry are 109.5°.

thats a little if u want the answer just look it up on google thats what i do haha : )
