In case of nitrogen, NCl3 is possible but not NCl5 while in case of phosphorus, PCl3 as well as PCl5 are possible.

(a) : 7N = 1s2 2s2 3p3 15P = 1s2 2s2 2p6 3s2 3p3 In phosphorus the 3dorbitals are available.

The compound formed in the positive test for nitrogen with the Lassaigne solution of an organic compound is

(a) : 3Na4[Fe(CN)6] + 4Fe3+  → Fe4 [Fe(CN)6]3 + 12Na+  Prussian blue

MnO42– undergoes disproportionation reaction in acidic medium but MnO4– does not. Give reason.

Mn has +7 O.S. which is maximum O.S. so MnO4 - can undergo reduction only while MnO4 2- has +6 O.S. of Mn so it can undergo oxidation as well...

A metal M does not liberate hydrogen from acids but reacts with oxygen to give a black colour product.

Cu does not liberate hydrogen from acids but reacts with oxygen to give black copper oxide. 2Cu + O2 → 2CuO Copper Oxide (black)
