# What is the molecular shape of phosphorus trichloride (PCl_3)? What are the bond angles in this molecule?

Mar 6, 2016

Trigonal pyramid, Tetrahedral, ${107}^{\circ}$.

#### Explanation:

The Lewis structure of $P C {l}_{3}$ is the following:

This is under the form of $A {X}_{3} E$ where $X$ represents the bounded groups $C l$ and $E$ represents the lone pairs.

The geometric shape is: Trigonal pyramid

The electron-pairs arrangement is: Tetrahedral

This is similar to the ammonia molecule $N {H}_{3}$.

The bond angle is equal to ${107}^{\circ}$.
