Given below are statements about some molecules/ions. Identify the CORRECT statements. A. The dipole moment value of NF ₃ is higher than that of NH ₃ . B. The dipole moment value of BeH ₂ is zero. C. The bond order of O ₂ ²⁻ and F ₂ is same. D. The formal charge on the central oxygen atom of ozone is -1. E. In NO ₂ , all the three atoms satisfy the octet rule, hence it is very stable. Choose the correct answer from t

Step-by-step solution

Statement A: In NH₃ , the orbital dipole due to the lone pair is in the same direction as the resultant dipole moment of the N-H bonds. In NF₃ , the orbital dipole is in the opposite direction to the resultant dipole moment of the N-F bonds. Thus, dipole moment of NH₃ ( 1.47 D ) is higher than NF₃ ( 0.23 D ). Statement A is incorrect. Statement B: BeH₂ is a linear molecule ( sp hybridization). The two Be-H bond dipoles are equal and opposite, so they cancel each other out, making the net dipole moment zero. Stateme
