Question

Two different bond lengths are observed in $P{F}_5$ molecule but only one bond length is observed in $S{F}_6$.

If true enter 1, else enter 0.

Answer 1

$PC{l}_5$ has trigonal bipyramidal structure in which bond angles of ${90}^{\circ }$ and ${120}^{\circ }$ exist. Hence, two types of bond length are observed, axial bonds are longer than the equatorial bonds while in case of $S{F}_6$, there is only one type of angle $\left({90}^{\circ }\right)$ and has octahedral structure.

Therefore, the statement is correct.
