Question

41. There can be two equivalent best resonance structures of ________. A) NO2- B) NO3- C) SO32- D) SO42- E) BrO3- 42. The electron pair in a H-F bond could be considered a) closer to H because hydrogen has a larger radius and thus exerts greater control over the shared electron pair b) closer to F because fluorine has a higher electronegativity than hydrogen c) closer to H because hydrogen has a lower electronegativity than fluorine d) an inadequate model since the bond is ionic e) centrally located directly between the H and F

Answer 1

(41) Thoo equivalent best resonance structeises -IA] Noz op B] Nas has three equivalent rescance stouctente LCJ sol has three equivalent resumance structerse 10] sole has Four equivalent resonance stoueteise TE) Boz has three egwvaleut resmance structure. (42) @ The electron pair in H-F band could be considered [b] closer to F because fluorine has higher electrone ga -tivity than hydrogen. F is more electronegative atom and His more electro positive them atom. So electocoa pair in H-F board could be considered closer to F .
