When the temperature increases the molecules of the liquid gain energy and kinetic energy increases, so it makes a pressure above the liquid
From electronic configuration valence electron of Nitrogen is 5, oxygen 6x2 which 12 since it involve two molecules , that of is frulorine is 7, and that No2F is 24 which is gotten form adding (5,12,7 ).All resonance structure are as follows
