P_2O_5 can dimerise but N_2O_5 cannot. Explain with structure. |

Answer» Solution :Nitrogen on account of small size and high. electronegativity has a strong tendency to form multiple bonds (`ppi-ppi`) with oxygen and form oxide in open chain structure. HOWEVER DUE to larger and diffused p-orbital, phosphorus is unable to construct such `pi`-bonds and prefers to form single bonds in order to gain STABILITY. As a result, `N_2O_5` does not undergo DIMERISATION whereas `P_2O_5` dimerises to form `P_4O_(10)` For structural detail |
