Question

The oxide without nitrogen-nitrogen bond is:

Options
  1. a

    N2O4\mathrm{N_2O_4}

  2. b

    N2O\mathrm{N_2O}

  3. c

    N2O5\mathrm{N_2O_5}

  4. d

    N2O3\mathrm{N_2O_3}

Correct Answerc

N2O5\mathrm{N_2O_5}

Detailed Solution

Strategy: Identify the Nitrogen oxide where central atoms are bridged by an Oxygen atom.

Step 1: Skeletal Analysis As established, \ceN2O,N2O3,\ce{N2O, N2O3,} and \ceN2O4\ce{N2O4} typically feature direct \ceNN\ce{N-N} associations in most/all of their stable forms.

Step 2: Detailed Structure of N2O5 \ceN2O5\ce{N2O5} (gas phase) consists of two planar \ceNO2\ce{-NO2} groups linked by an oxygen atom bridge: \ceO2NONO2\ce{O2N-O-NO2}. There is no direct bond between the two Nitrogen atoms.

Answer: (Option) [c] \ceN2O5\boxed{\text{Answer: (Option) [c] $\ce{N2O5}$}}
