High Explosives

1)C6H3(NO2)3

2)H2SO4 is a lewis acid; HNO3 is a lewis base
H2SO4 + HNO3 --> [HSO4]- + [H2NO3]+
[H2NO3]+ --> H2O + [NO2]+
[NO2+], a electropile prepared for nitraton( a type of electropilic substitution)

3) --OH- and --CH3 are electron withdrawing and donating resp. offering activating effect for the carbocation intermediate of certain orientations. thus, methybenzene and phenol are more energetically feasible than benzene w.r.t. electrophilic subst.

4)nitro group is highly electron withdrawing that intensifies the density of the positive charge in the carbocation intermediate and destablizes itself energetically. when first nitro group is attached to the aromatic part, the next will be harder to attach because of te above reason

5)NH4NO3 contains a surplus of oxygen which TNT can use during explosion

6)(guess) in the absence of oxygen
because explosion usually involves oxygen

7)C6H2(NO2)3O-Na+
