Esterification Reaction
Write a chemical equation to illustrate the following name reaction:
Esterification reaction

Solution 1
Carboxylic acid + Alcohol `->` Ester + Water
For example:
\[\ce{CH3COOH + C2H5OH -> CH3COOC2H5 + H2O}\]
Solution 2
Esterification reaction is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water in acidic mediums usually. The general reaction is as follows:
\[\begin{array}{cc}
\ce{O}\phantom{.............................................}\ce{O}\phantom{............................}\\
||\phantom{.............................................}||\phantom{............................}\\
\ce{\underset{Acid}{RC} - OH + \underset{Alcohol}{R'OH} ->[conc. H2SO4][heat] \underset{Ester}{RC - O - R'} + \underset{Water}{HOH}}\\
\end{array}\]

Raina while doing certain reactions observed that heating of substance ‘X’ with a vinegar-like smell with a substance ‘Y’ (which is used as an industrial solvent.) in the presence of conc. Sulphuric acid in a water bath gives a sweet-smelling liquid ‘Z’ having molecular formula C4H8O2. When heated with caustic soda (NaOH), ‘Z’ gives back the sodium salt and the compound ‘Y’.
