Question

1. The stretching frequency of a carbonyl (C=O) bond in a typical ketone is 5.15 × 1013 Hz. The vibrational energy of the molecule increases when light of this frequency is absorbed. a) What is the wavelength of this light in nanometers? Use b) What is the wavelength of this light in micrometers? Solve for lambda c) Express the frequency of this light in wavenumbers. Solve for lambda d) What is the energy (in joules) of a single photon of light at this frequency? Ephoton = hv
