Nitrogen tribromide Nitrogen bromide

Bromine trichloride

Dinitrogen pentoxide

Nitrogen and oxygen, both are non-metals. They do not form ionic bonds or metallic bonds together. One of the oxygen connects the two nitrogen atoms. Thus, N2O5 have both covalent and coordinate covalent bonds.

N2O4 has an irritating, unpleasant acid-like odor. N2O4 is a very reactive, toxic oxidizer.

Dinitrogen tetroxide is a one of the oxide of nitrogen and are two nitrogen atoms are located at center of the molecule. In Lewis Structure of N2O4, two oxygen atoms have connected to one nitrogen atom. There are charges on atoms in Lewis Structure of N2O4.

Dinitrogen tetroxide

Dinitrogen Tetroxide (Nitrogen dioxide) Explosion limits : Non flammable.

Highly toxic; [Quick CPC] Like other nitrogen oxides, inhalation of NO4 may induce delayed pulmonary edema. Concentrations of 25-50 ppm cause irritation of the eyes and nose while 50-100 ppm can cause pulmonary edema and death.

N2O4 is dinitrogen tetroxide while NO2 is nitrogen dioxide. Further, N2O4 occurs as a liquid, while NO2 is a gaseous substance. Moreover, N2O4 is a colourless liquid while NO2 is a brown gas.
