In experiment 6 we will perform a fischer esterification (vollhardt, chapter 9-4 and 19-9). suggest what could happen if you were to attempt recrystallization of a carboxylic acid with ethanol or an ester with water.

Acid-Catalyzed Ester Hydrolysis

Explanation:

Fischer Esterification is a reversible reaction and the Le Châteliers principle can be used for the reaction to be completed. For the reverse reaction of Fischer Esterification, using the hydrolysis of ethyl ethanoate, the steps involved are:

1) An hydrogen ion is added to the ester and one of the lone pairs on the oxygen double-bonded to the carbon atom takes the hydrogen ion.

2) The lone pairs on the oxygen of a water molecule takes the positive charge on the carbon atom.

3) The hydrogen ion is transferred from one oxygen atom to another.

4) Then an ethanol molecule is released (one of the products).

5) Reaction with a water molecule releases hydrogen from the oxygen and the other product (ethanoic acid) is formed.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
