Homework Answers
The compound is saturated and can be an alcohol(-OH) , as the -OH proton is labile with D2O and gets exchanged . The resonance of -OH proton also occurs in the region 2- 5 ppm.
Thus we can say the compound is isopropanol CH3-CH(OH) -CH3
From the 1HNMR
we see both the -CH3 as doublet at 1.1 ppm,
the middle CH , is seen as a heptet at 4.0 ppm(deshielded due to the attached -OH)
and the oH proton at 2.2ppm that disappears on addition of D2O.
