According to the VSEPR theory, the actual F -As -F bond angles in the AsF₄^- ion are predicted to be A)109.5° B)90° and 120° C)180° D)< 109.5° E)< 90° and < 120°

Quizplus · Accepted Answer

The AsF4^- ion has a seesaw shape due to the presence of one lone pair on the central arsenic atom. This results in bond angles that are slightly less than the ideal 90° and 120° due to lone pair-bond pair repulsion.
