Which of the following statements is true? (i) The two axial P - Cl bonds in PCl ₅ are longer than the three equatorial bonds. (ii) The axial bonds in PCl ₅ are stronger than equatorial bonds. (iii) The axial bonds in PCl ₅ are more stable than equatorial bonds. (iv) All five bonds in PCl ₅ molecule are equivalent.

Options

  1. A(i)
  2. B(ii)
  3. C(iii)
  4. D(iv)

Correct answer

A. (i)

Step-by-step solution

In 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^ angle to 3-equatorial bonds, while all equatorial bonds are at 120^ angle to each other.
