Triphenylmethanol color
WebRecord all measurements and color changes. Weigh approximately 0.200 g of the triphenylmethanol (TPM) and place into a reaction tube. Using separate glass pipettes, add 4 mL of acetic acid and then 0.60 mL of hydrobromic acid (33% solution in acetic acid)to the same reaction tube. Then, heat the mixture for 5 WebThe resulting color is determined by this gap. Changing the HOMO-LUMO energy gap will change the wavelength absorbed by the molecule as well, resulting in a change of color. Questions: 1. When benzophenone is added to the Grignard solution, a white precipitate known as a magnesium salt from the triphenylmethanol is formed. 2.
