1. Explain how does adding a small amount of a girgnard reagent solution to a Girgnard reaction help the reaction get started. Explain the presence of water is a major reason a Grignard might not start.
2. State the reaction that would lead to formation of butane from the Girgnard reagent formed form 1-bromobutane.
Calculate the solubility of Ca(OH)2 in a 0.469M CaCl2 solution at 31°C, given that the Ksp of Ca(OH)2 is 4.96 x 10-6 at that temperature. Give your answer in milli Molar units
