The structures of two compounds and the measured approximate ratio of 1H-NMR spectrum signal areas for one of the compounds are shown
Which compound was responsible for the 1H-NMR spectrum?
Ratio of 1H-NMR spectrum signal areas = 40:40:20
fluoro-benzene.
or
hexane

It is fluorobenzene
There are five H . The areas are proportionnal to the number of H
If you add all the area you find 100 divide by 5 =20
so in H the signal 20 comes from hydrogen in position para versus fluorine , and tere are two H on position meta and ortho

Sounds like the fluoro-benzene, if it has a series of short peaks all bunched together it is definetely your answer....this is do to the benzene H's properties....
