1.	What is the oxidation number of the underlined atoms in each of the following molecules / ions ? (a)ulClO_3^(-) (b) ulBrF_3 (c) ulCH_4 (d) ulC_6H_(12)O_6 (e) Na_2ulB_4O_7 (f) Na_4\|__Fe(CN)_6] (g) ulN_2H_4.
Answer» Solution :Suppose x be the oxidation number of the UNDERLINED atom : `{:((a),ClO_3^(-),x+(-2xx3)=-1),(,,x-6=-1" or "x=+5),((b),BrF_3,x+(-1xx3)=0),(,,x-3=0" or "x=+3),((c),CH_4,x+1(1xx4)=0),(,,x+4=0" or "x =-4),((d),C_6H_(12)O_6,6xxx+1xx12+(-2xx6)=0),(,,6x+12-12=0" or "x=0),((e),Na_4[FE(CN)_6],(+1xx2)+(xxx4)+(-2xx7)=0),(,,+2+4x-14=0 " or "x=+3),((f),Na_4[Fe(CN)_6],(+1xx4)+x+1(-1xx6)=0),(,,+4+x-6="or "x=+2),((G),N_2H_4,2x+4=0" or "x=-2):}`
