Question

Which of the following set of properties belong to $PC{l}_5$ ?

• A. $s{p}^3,$ tetrahedral, 4 valence shell pairs of electrons
• B. trigonal bipyramidal, 5 valence shell pairs of electrons
• C. $s{p}^3{d}^2,$ octahedral, 6 valence shell pairs of electrons
• D. $s{p}^{3}d,$ square planar, 4 valence shell pairs of electrons

Answer 1

Answer: (B)

$PC{l}_5$ molecule has $s{p}^{3}d$ hybridisation. Its geometry is trigonal bipyramidal and it has $5$ valence shell pairs of electrons.
