To prepare a solution of NaCl, you weigh out 2.634(±.002)g and dissolve it in a volumetric flask whose volume is 100.00(±0.08)ml. Express the molarity of the solution, along with its uncertainty, with an appropriate number of digit.
Write a balanced equation for each of the two steps of the reaction, namely: (1) the reaction between benzyltriphenylphosphonium chloride and sodium hydroxide
Treatment of ethyl isobutyrate with ethoxide in ethanol, followed by mild acidic workup, leads to recovery of starting material rather than a Claisen Condensation product. Please explain this observation, using structures rather than words as much..
