Which of the following statements is true?
(i) The two axial \(\mathrm{P}-\mathrm{Cl}\) bonds in \(\mathrm{PCl}_5\) are longer than the three equatorial bonds.
(ii) The axial bonds in \(\mathrm{PCl}_5\) are stronger than equatorial bonds.
(iii) The axial bonds in \(\mathrm{PCl}_5\) are more stable than equatorial bonds.
(iv) All five bonds in \(\mathrm{PCl}_5\) molecule are equivalent.
- A (i)
- B (ii)
- C (iii)
- D (iv)
Answer & Solution
Correct Answer
(A) (i)
Step-by-step Solution
Detailed explanation
In \(\mathrm{PCl}_5\), there are three equatorial bonds and two axial bonds. The axial bonds are longer than equatorial bonds because of greater repulsion from equatorial bonds. The 2 -axial bonds are at \(90^{\circ}\) angle to 3-equatorial bonds, while all equatorial bonds are…
