Question

question 6 of 8
which molecule or ion has a bent shape?
a. pcl5
b. clo4-
c. of2
d. ph3

Explanation:

To determine the molecular shape, we use the VSEPR (Valence - Shell Electron - Pair Repulsion) theory. For $PCl_5$, the central P atom has 5 bonding pairs and 0 lone pairs, giving a trigonal - bipyramidal shape. For $ClO_4^-$, the central Cl atom has 4 bonding pairs and 0 lone pairs, resulting in a tetrahedral shape. For $OF_2$, the central O atom has 2 bonding pairs and 2 lone pairs. According to VSEPR, this leads to a bent shape. For $PH_3$, the central P atom has 3 bonding pairs and 1 lone pair, giving a trigonal - pyramidal shape.

Answer:

C. $OF_2$
