Answer #1

Molecular formula = C4H10O2

Sites of unsaturation = 0

Out of given spectra, Spectra a possess 10 protons. Others does not contain the required protons therefore, given molecular formula matches with Spectra A

Molecular formula = C7H7Br

Sites of unsaturation = 4 (indicates aromatic ring present)

Out of given spectra, spectra b and d contain aromatic protons but only spectra b contain 7 protons in it

therefore, given molecular formula matches with Spectra B

Molecular formula = C4H9Br

Sites of unsaturation = 0

Out of given spectra, spectra C contain 9 protons in it

therefore, given molecular formula matches with Spectra C

Molecular formula = C8H9Br

Sites of unsaturation = 4 (aromatic ring present)

Out of given spectra, spectra D contain 9 protons in it and presence of aromatic ring in it.

therefore, given molecular formula matches with Spectra D
