Answer 1

Part A) 109.5 degrees Part B) 90 degrees Part C) 120 degrees Part D) 180 degrees

Step-by-step explanation:

In order to determine the molecular geometry of compounds, the lone electron pair and number of atoms attached to the central atom are considered. Thus:

Part A) For SiCl4, it has a tetrahedral molecular geometry, therefore the bond angles are 109.5 degrees.

Part B) For ICI4-, it has a square planar molecular geometry and the value of the smallest bond angle is 90 degrees.

Part C) For AlCl3, it has a trigonal planar molecular geometry and its bond angle is 120 degrees.

Part D) For XeCl2, it has a linear molecular geometry and its bond angle is 180 degrees.
