A) XO, lower B) XO, higher C) X20, lower

Answer 1

sch Ans is option (C) N. now from Reasone B, and a chave electrone according to 586, Here in table shoros torey 7IE. from No, and F Fluorine have highest electronegati- Vity. it com noe ionised as positive charge. N and o, oxygen has total of electon în intom and in od 4 election in ap orbital and Nitrogen total 7 electon present and in ap arbitel there is 3 electron present, it is most stuble because hadt filled orbital, compare to oxygen, and it require more energy compare to oxygen toomed ionised X Lewis structure l oxygen хуви •3. 102 (4) structure when xi bonded to oxygen the bond will have the formula xo .If a nasa bonded to suffer in strand, it would have a lower melting point compared to being bonded to oxygen Reasan : •• x=0 .X xo bond have more ionic Churucter com perme XS bond. în group go up to down ionil Character decrease, and be din decrease ionic Chomucher ausu decreerse meeting point.
