White phosphorus is very reactive, but not the red one. Why? |
|
Answer» Solution :White phosphorus is very reactive, DUE to the P-P-P bond angle strain at 60° Red phosphorus is very STABLE, due to chain like polymeric structure. P.1,6 Maximum covalency of nitrogen is four. Explain. Solution Nitrogen has no valence d-orbitals. Excitation of 2s electron to 3s orbital is difficult. Hence nitrogen does not form five bonds. `N(Z = 7): [He] 2s^(2)2p^(1)2p^(1)2p^(1)` Nitrogen can form three covalent bonds and one dative bond as in `NH_(4)^(+)` or in `C_(6)H_(5)NH^(+)` ions. Its maximum covalency is four. |
