Why does nitrogen show anomalous behavior? Discuss the trend of chemical reactivity of group 15 elements with oxygen, halogens, and metals.
Nitrogen shows anomalous behaviour because lone pair to lone pair is minimized. Reactivity towards oxygen: group 15 elements form oxides E2O3&E2O5E2O3&E2O5 . in these type of oxides, when the oxidation state of this group element is higher was more acidic than with lower oxidation state. Down the group, acidic character decreases. Reactivity towards halogens: these group elements form salts EX3&EX5EX3&EX5 . Except N, all elements in this group form EX5EX5 due to lack of d-orbital in it. All trihalides are stable except nitrogen trihalide. Reactivity towards metals: these group elements form binary compounds with metals with oxidation state of -3
