kap26 [50]

Answer:

31.1°C

Explanation:

Given parameters:

  Temperature = 88°F

The formula of the to convert is:

         T°F = T°C - 32  / 1.8  = \frac{TC - 32}{1.8}

Now input the parameters and solve;

       T°F =\frac{ 88  -32}{1.8}

      T°F = 31.1°C

Which combination of reactants will produce ethyl 3-phenyl-3-oxopropanoate when treated first with an alkoxide and then with a d
Nezavi [6.7K]

Ethyl acetate and methyl benzoate combination of reactants will produce ethyl 3-phenyl-3-oxopropanoate when treated first with an alkoxide and then with a diluted aqueous acid

<h3>Ethyl acetate</h3>

One of the most straightforward carboxylate esters is ethyl acetate. The simplest is methyl formate, a former Molecule of the Week. Most people enjoy the taste and aroma of the colorless liquid's sweet, fruity scent.

Ethyl acetate was initially created by combining ethanol and acetic acid, as one might anticipate. The process was the traditional Fischer esterification, which dates back to 1895 and is catalyzed by an acid. This commercial synthesis is still the most popular. A different approach is the Tishchenko reaction, in which acetaldehyde disproportionately reacts with base to form alcohol and acid, which subsequently esterify naturally.
