    I would be very appreciative to anyone who may be able to help me with this...:)

    1.How would you separate phenol and 1-ethoxybenzene from a mixture?

    2. How you would take a melting point of a crystalline product.

    3. Why a color change occurs when triphenylmethane dyes are exposed to different pH levels.

    4. Can infrared spectroscopy be used to distinguish between endo and exo isomers? Why or why not?

    This sounds suspiciously like ochem homework ;]
    1. acid/base extraction
    2. melting point calorimeter
    3. photon absorbance of protonated vs unprotonated forms occurs at different wavelengths
    4. technically yes, practically no; chirality will affect orbital overlap, but it's difficult to distinguish without knowing the spectra of the compounds beforehand
