Question

identify the following: -CH stretch and bends -Hybridization (sp, sp2, sp3) -Other major functional groups correctly (i.e carbonyl, amine, phenyl ring, etc...)

Answer 1

- 1 * The absorptions at 3091.91 and 3060.93 cm' are assigned to aromatic C-H stretching vibrations (sp² C-H stretching The weak absorption bands at 2968.83 cm' and 2857 cm are assigned to sp3 C-H stretching vibrations. The bands at 1594, 1572, 1503 cmt represents the sp²c=c stretching vibrations (skeletal Vibrations of the aromatic ring) * the absorptions at 1445, 1368 ont corresponds to bending Vibrations of she cH * The band at 1268 ent exhibits &C-n stretching vibration (anomatic) the band at liss ant is due to sfc.n stretching inbration. Caliphatic) The absorptions (strong> at 744 ont (sp²c. H out of plane bending and 688 cmt (sp²c-c out of plane bending) suggests a mono substituted benzene ling.
