I am struggling to decipher these spectrums, can you
help?
1H NMR Data
7.9 (d, J = 8 Hz, 2H) indicates aromatic protons attached ortho to electron withdrawing group attached to benzene ring
7.25-7.60 (m, 3H) remaining three aromatic protons (mono substituted aromatic ring present)
2.95 (t, 2H) (CH2 group attached to electron withdrawing group)
1.71 (quintet, 2H) (CH2 attached to two CH2)
1.42 (sextet, 2H) (CH2 attached to CH2 and CH3)
0.95 (t, 3H) (CH3 attached to CH2)
13C NMR data
