What is the oxidation state of nitrogen in N2O5? Hence by the basic principle of quantum mechanics we can say that in N2O5 nitrogen has + 4 oxidation state . NOTE: Formulae are made to simplify the things. But they have some limitations But in order to overcome those limitations one must use the basics of the subject. Let the oxidation state of N be x. Oxidation state of O is -2 as it is in oxide form. ⇒ 2x+5(−2) =0. ⇒ x = 210. . Pure solid N2O5 is a salt consisting of separated linear nitronium ions NO2 and planar trigonal nitrate anions NO3 . Both nitrogen centers have oxidation state +5. It crystallizes in the space group D 6h (C6/mmc) with Z = 2 with the NO 3 anions in the D3h sites and the NO 2 cations in D3d sites. The vapor pressure P (in torr) as a function of temperature T (in kelvin) in the range 211 to 305 K is well approximated by the formula ${\displaystyle \ln P=23.2348-7098.2/T}$ Pure solid N2O5 is a salt consisting of separated linear nitronium ions NO2 and planar trigonal nitrate anions NO3 .

The vapor pressure P (in torr) as a function of temperature T (in kelvin) in the range 211 to 305 K is well approximated by the formula ${\displaystyle \ln P=23.2348-7098.2/T}$ being about 48 torr at 0 °C 424 torr at 25 °C and 760 torr at 32 °C (9 degrees below the melting point). In the gas phase or when dissolved in a nonpolar solvents such as CCl4 the compound exists as covalently bound molecules O2N–O–NO2. In the gas phase theoretical calculations for the minimum-energy configuration indicate that the O–N–O angle in each NO 2 wing is about 134° and the N–O–N angle is about 112°. In that configuration the two NO 2 groups are rotated about 35° around the bonds to the central oxygen away from the N–O–N plane. The molecule thus has a propeller shape with one axis of 180° rotational symmetry (C2) When gaseou...
