Current Question (ID: 10715)

Question:

$\text{False statement regarding PCl}_5 \text{ is:}$

Options:

1. $\text{PCl}_5 \text{ molecule is non-reactive.}$ (Correct)
2. $\text{Three equatorial P-Cl bonds make an angle of 120° with each other.}$
3. $\text{Two axial P-Cl bonds make an angle of 180° with each other.}$
4. $\text{Axial P-Cl bonds are longer than equatorial P-Cl bonds.}$

Solution:

$\text{Hint: Axial bonds is longer than equatorial bonds.}$ $\text{The structure of PCl}_5 \text{ is as follows:}$ $\text{Yes, the three equatorial P — Cl bonds make an angle of 120° with each other.}$ $\text{Yes, two axial P — Cl bonds make an angle of 180° with each other.}$ $\text{Yes, axial P — Cl bonds are longer than equatorial P — Cl bonds.}$ $\text{PCl}_5 \text{ molecules are highly reactive. On heating, it undergoes a decomposition reaction and forms PCl}_3 \text{ and Cl}_2\text{.}$
