Work Step by Step
a. $PCl_{3}$:
The molecular structure of $PCl_{3}$ is trigonal bipyramidal. The phosphorus (P) atom is the central atom, and it forms three equal bonds with the three chlorine (Cl) atoms. The bond angles between the chlorine atoms are approximately 107 degrees.
b. $SCl_{2}$:
The molecular structure of $SCl_{2}$ is bent or angular. The sulfur (S) atom is the central atom, and it forms two bonds with the two chlorine (Cl) atoms. The bond angle between the chlorine atoms is approximately 104 degrees.
c. $SiF_{4}$:
The molecular structure of $SiF_{4}$ is tetrahedral. The silicon (Si) atom is the central atom, and it forms four equal bonds with the four fluorine (F) atoms. The bond angles between the fluorine atoms are 109.5 degrees.
