Identify the correct orders against the property mentioned:A. H_{2} O > NH_{3} > CHCl_{3} - dipole momentB. XeF_{4} > XeO_{3} > XeF_{2} - number of lone pairs on central atomC. O-H > C-H > N-O - bond lengthD. N_{2} > O_{2} > H_{2} - bond enthalpyChoose the correct answer from the options given below :

Solution & Step-by-step Explanation

Let's evaluate each order:A: Dipole moment follows H_{2} O (1.85 D) > NH_{3} (1.47 D) > CHCl_{3} (1.01 D) . This is correct.B: Lone pairs: XeF_{4} (2), XeO_{3} (1), XeF_{2} (3). The order should be XeF_{2} > XeF_{4} > XeO_{3} . This is incorrect.C: Bond lengths: O-H \approx 96 pm, C-H \approx 109 pm, N-O \approx 120 - 140 pm . The order is incorrect.D: Bond Enthalpy: N_{2} (triple bond) > O_{2} (double bond) > H_{2} (single bond). This is correct.Correct options are A and D.
