Question

Which of the following will have the molecular shape of a trigonal bipyramid?

• A. $P{F}_{3}C{l}_2$
• B. $I{F}_5$
• C. $Br{F}_5$
• D. $Sb{F}_2^{2-}$

Answer 1

Answer: (A)

$P{F}_{3}C{l}_2$

Trigonal bipyramid geometry is possessed by a molecule in which the central atom has $5$bp and no lone pairs. In the given options, the correct answer must have a total of $10$ electrons in the valence shell of the central atom and must have made $5$ bonds with other atoms

$\therefore$ $P{F}_3{Cl}_2$ has a trigonal bipyramid geometry.
