When choosing unknown organic substances which are critric acid, acetone, urea, benzaldehyde, glycerol, and MTBE Write one or two paragraphs summarizing this experiment of properties of organic substances and see what results they got using the numerical data obtained and calculated to support the claims.

student found a bottle of unknown origin in the basement of an "CAUTION—contains С₁H₁O.” No other A old house. The bottle was labelled information was given, but inside the bottle were some white crystals. The student took the bottle to a chemistry laboratory, where she analyzed the crystals with the help of the laboratory staff. C₁2H₁6O reacted with Br₂ in CCl4 adding one mole of Br, and forming C₁₂H₁OB2₂. When a sample of C₁₂H₂O was reacted with O3 followed by Zn/H₂O, two different samples, J and K, were obtained. Compound J had a molecular formula of C.HgO₂, and its NMR is shown below. Compound K had a molecular formula of C₂H₂O, and it could be oxidized to compound L, with a molecular formula of C₂H₂O₂. The IR spectrum of L showed a very wide, strong band centred around 3000 cm*¹. The NMR spectrum of L showed only two different absorptions: a doublet (6H) at 0.9 ppm and a septet (1H) at 3.6 ppm. There was also a singlet (1H) off the scale at 11.8 ppm. students, deduce possible…

A new compound has the empirical formula GaCl2. Thissurprises some chemists who, based on the position of gallium in the periodic table, expect a chloride of gallium to have the formula GaCl3 or possibly GaCl. They suggest that the “GaCl2” is really Ga[GaCl4], in which the bracketed group behaves as a unit with a -1 charge. Suggest experiments to test this hypothesis
