उत्तर १
Carboxylic acid + Alcohol `->` Ester + Water
For example:
\[\ce{CH3COOH + C2H5OH -> CH3COOC2H5 + H2O}\]
उत्तर २
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:
\[\begin{array}{cc}
\ce{O}\phantom{.............................................}\ce{O}\phantom{............................}\\
||\phantom{.............................................}||\phantom{............................}\\
\ce{\underset{Acid}{RC} - OH + \underset{Alcohol}{R'OH} ->[conc. H2SO4][heat] \underset{Ester}{RC - O - R'} + \underset{Water}{HOH}}\\
\end{array}\]
