6. Question & Answer
  • Polar molecule contains bond dipoles, which do not cancel each other. Therefore, CH3COOCH2CH3 contains two polar bonds(CO and CO) in which their bond dipoles do not cancel each other. Hence, ethyl acetate is a polar compound. NB: Relative electronegativity determines whether a compound is a polar o...
  • Seperate the given acetaldehyde solution in two parts. Oxidize one of the solution using any oxidizing agent(KMnO4 etc.) and you will get the acetic acid CH3COOH. CH3CHO + KMnO4 +H2SO4 ——→ CH3COOH Reduce the second solution using any reducing agent (NaBH4, LiAlH4, etc.) the reduction of acetalde...
  • The answer is yes and what follows is the basis for that assertion. For ethyl acetate (EtOAc), saponification yields ethanol (EtOH) and sodium acetate (NaOAc) the reaction under consideration is shown below: EtOAc → EtOH + NaOAc The ∆G of formation of EtOAc is -557.3, of EtOH is -324.7, and NaOAc ...
  • Yes, but the esterification under those conditions is a reversible reaction, so complete conversion to the ester + water doesn't happen. I made a solution of acetic acid and ethanol in water, to clean print heads if I recall correctly, and when I went to use it some weeks later, it smelled strongly...
