To arrive at the molecular formula and at the structural formula the different steps involved are
(a) Qualitative analysis, (b) Quantitative analysis
In the qualitative analysis the different steps involved are
(a) Extra element detection
(b) Functional group analysis
In the quantitative analysis the percentage of every element is determined and then the emperical and molecular formulae are determined. Both these are followed by structural elucidation.
The number of `-OH` groups in a compound not containing any other functional group can be determined by
A. `CH_(3)COCl`
B. `CH_()MgBr`
C. `CH_(3)OCH_(3)`
D. Both (a) and (b)
