Show Solution

Correct Answer: 2

Solution and Explanation

PCl₃+ C2H₅OH → C₂H₅Cl + H₃PO₃

(A)

H₃PO₃ + PCl₃→ H₄P₂O₅

(A) (B)

Structure of H₄P₂O₅

Hybridisation

Statement I: Since fluorine is more electronegative than nitrogen, the net dipole moment of NF₃ is greater than NH₃.
Statement II: In NH₃, the orbital dipole due to the lone pair and the dipole moment of NH bonds are in opposite directions, but in NF₃, the orbital dipole due to the lone pair and the dipole moments of N-F bonds are in the same direction.
In light of the above statements, choose the most appropriate from the options given below:
