When molecules and energy interact, there are different results. Atoms may dissociate, a molecule may rotate, or bonds may stretch and bend. Carbon dioxide has four possible vibrations. What is the effect of each vibration on the molecule: stretching, bending, or breaking?
Define A mixture of benzoic acid, benzyl alcohol, and biphenyl is spotted on a silica gel TLC plate and developed in a dichloromethane-cyclohexane solvent mixture. Forecast the relative Rf values for the three components in the sample.
