I synthesized 4-methylcyclohexene + H20 from 4-methylcyclohexanol also an acid catalyst. In the experiment, 1.0ml of saturated sodium chloride is utilized to rinse the Hickman head after initial distillation. Explain what is saturated sodium chloride, rather than pure water, utilized for this procedure and the subsequence washing of the organic layer?
Pure benzophenone freezes at 48.1 celcius of 1.25 g of biphenyl (C12H10) molar mass= 1542 g/mol) with 25.38 g of benzophenone forze at 16.8 celcius. calculate the molarity of the solution (m) and the molal freezing point depression constant (Kf). ..
