On the course website are the IR spectra of the starting material and product. Identify the differences between the two spectra by estimating the frequencies of the OH and C-O stretches for cyclohexanol and the frequency of the C.

Ido not understand. 

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
