a) 2-Hydroxy-2-methylpentanal Interpretation: Whether 2-hydroxy-2-methylpentanal is an aldol condensation product or not is to be stated. The aldehyde or ketone precursor from which it can be prepared also is to be stated. Concept introduction: Aldehydes and ketones with α-hydrogen undergo a base catalyzed carbonyl condensation reaction in aldol condensation. In this reaction two molecules of the reactant combine by forming a bond between α-carbon of one molecule and the carbonyl carbon of the second molecule. The product obtained is a β-hydroxyaldehyde or ketone. To state: Whether 2-hydroxy-2-methylpentanal is an aldol condensation product or not. Further to state the aldehyde or ketone precursor from which it can be prepared.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

at 32.0 °C? What is the osmotic pressure (in atm) of a 1.46 M aqueous solution of urea [(NH2), CO] at 3 Round your answer to 3 significant digits.

Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a. Compare the solution concentrations expressed as ppm Zn and ppm Zn(NO3)2. Compare the concentrations expressed as M Zn and M Zn(NO3)2 - Which units allow easy conversion between chemical species (e.g. Zn and Zn(NO3)2)? - Which units express concentrations in numbers with easily expressed magnitudes? - Suppose you have an analyte for which you don't know the molar…
