Question

50. The nitrite ion, NO can be represented as a resonance hybrid of two significant Lewis structures. Which statements about this are correct? I. The two resonance structures contribute equally to the Structure. II. The formal charge of nitrogen is zero in both resonance structures. (A) I only (B) II only (C) oth I and II (D) Neither I nor II 51. Which is not a stable molecule? (A) NF (B) NF (C) PF. (D) PF 52. What is the molecular geometry of IF 3? (A) Trigonal planar (B) Trigonal pyramidal (C) shaped

Explanation / Answer

51) in both the resonance structures, nitrogen is not neutral. Therefore option A is the answer

52) NF5 is not a stable molecule since nitrogen is slightly stable molecule and hence can not form 5 bonds

53) The molecular geometry of IF7 is Pentagonal bipyramidal molecular geometry
