Presume you were asked to carry out an aldol condensation reaction between benzaldehyde as well as pentanal, modeled subsequent to the experiment you performed with benzaldehyde and acetone. Explain what product would you expect to make? Intend a detailed reaction mechanism for this reaction. Explain what by-product might be expected in this experiment?
If you combine equal volumes of the following solutions, which combinations will result in the desired buffer? Why are the answers are 0.20 M CH3CO2H + 0.10 M NaOH and 0.20 M Na(CH3CO2) + 0.10 M HCl
When optically active B was treated with CrO3 in pyridine, an optically inactive sample of A was obtained. Heating A with hydrazine in base gave hydrocarbon C, which, when heated with alkaline KMnO4, gave carboxylic acid D. Identify compounds A, B..
the degree of agreement among several measurements of the same quantity is called. it reflects the reproducibility of a
Burns cause by steam at 100 degrees can be more severe than those caused by water same temperature because steam contains more heat than water
