Reaction of Grignard reagent, C?H?MgBr with C?H?O followed by hydrolysis gives compound "A” which reacts instantly with Lucas reagent to give compound B, C??H??Cl. The compound B is:

 

ATP has phosphate group, PO? ³?
So x + 4 (– 2) = – 3 or x = + 5

2 Pb (NO? )? → 2PbO + 2NO? + O?
2NO? → N? O? colourless
N? O? + 2NO → 2 N? O?
Oxidation state in N? O? is +3

$=\frac{{10}^{14}}{{10}^3}={10}^{11}$

$\mathrm{}\underset{2\mathrm{x}-2=0}{{\mathrm{K}}_2\mathrm{O}?\mathrm{x}=+1}$

$\underset{2\mathrm{x}-2=0}{{\mathrm{K}}_2{\mathrm{O}}_2}?\mathrm{x}=+1$

CrO? ²? (Cr? ) → Cr? ³, Total oxidation number change = 3
MnO? (Mn? ) → Mn? ², Total oxidation number change = 5
Cr? O? ²? (Cr? ) → 2Cr? ³, Total oxidation number change = 6
C? O? ²? (C? ³) → 2CO? (C? ), Total oxidation number change = 2
