solution:
The given specta of the unknow compound of the additive gasoline in the pure state are determined from the given spectral data is
[tex]\delta 0.9 triplet Area=3H\\
\delta 1.5 sextet area=2H\\
\delta 3.2 triplet,area =1H\\
\delta 3.5 quartert,area=2H\\
form the above spectral data the structure of the compound is\\
(3.5,q)(3.2,t)\\[/tex][tex]
CH_{3}---CH_{2}---CH_{2}---OH\\
As the compound is very sample so there is interaction between the alcoholic proton and methylene proton.[/tex]
