In what portion(s) of the IR spectrum shown below would you find signal(s) from R-NH2? A graph plots wavenumber in centimeters to the power negative 1 on the horizontal axis and percentage transmittance along the vertical axis. The horizontal axis ranges from 4000 to 500 in equal increments. The vertical axis ranges from 0 to 100 in increments of 20. The area between 3250 to 3350 wavenumbers is labeled A. The area between 3000 to 3150 wavenumbers is labeled B. The area between 2850 to 3000 wavenumbers is labeled C. The area between 2700 to 2850 wavenumbers is labeled D. The area between 2100 to 2300 wavenumbers is labeled E. The area between 1650 to 1800 wavenumbers if labeled F. The area between 1550 to 1650 wavenumbers is labeled G. Select answer from the options below G A E F D B C
