Mass
Percentage of carbon = 29.30%
Percentage of hydrogen = 5.74%
Empirical formula calculation
Atomic ratio of carbon = 29.30 / 12 = 2.44
Atomic ratio of Hydrogen = 5.74 / 1 = 5.74
Dividing each number with the smallest number (C:H)= (2.44/2.44): (5.74/2.44)
(C:H)= (1 : 2.3)
Molecular formula = empirical formula * 3= C3H7
Mass spectra indicates presence of bromine Thus Molecular formula is C3H7Br
Mass spectra
M+ = 122, 124 (1:1) presence of bromine
M-79 ( loss of bromine) peak, that is (M = 43) is observed in mass spectrum
1H NMR spectra
4.2 (septet, 1H) proton attached to six proton (two equivalent CH3)
1.8 (d, 6H) Two equivalent CH3 attached to CH
All above data indicates following structure
