Question

From the electronic configurations, one can predict that the geometric configuration for which of the following molecules is not correct?

• A. $P{F}_3$, trigonal planar
• B. $C{F}_4$, tetrahedral
• C. $CHC{l}_3$, irregular tetrahedron
• D. $O{F}_2$, bent (v-shaped)
• E. $HF$, linear

Answer 1

The correct option is A $P{F}_3$, trigonal planar

In $P{F}_3$, the central P atom has one lone pair of electrons and 3 bond pairs of electrons. It undergoes $s{p}^3$ hybridisation which results in tetrahedral electronic geometry and pyramidal molecular geometry.
