N-propylbenzene, C6H5CH2CH3, contains C (sp3) -H and C (sp2) -H bonds. Its IR spectrum shows strong or medium absorptions at 3085, 3064, 3028, 2960, 2931 and 2873 cm ^ -1, as well as bands below 1600cm -1. Which statement is wrong? A.) Stretching of the C (sp3) -H bonds results in absorptions at lower wave numbers than the stretching of the C (sp2) -H bonds. B.) The absorptions at 2960, 2931 and 2873 cm ^ -1 are assigned to stretching of the C (sp3) -H bonds. C.) The absorptions at 3085, 3064 and 3028 cm ^ -1they are assigned to stretching of the C (sp2) -H bonds. D.) Each absorption can be assigned to the stretch mode of a particular bond in the propylbenzene molecule.
