Carbon and its Compounds is the conceptual gateway to organic chemistry in CBSE Class 10.
Esterification vs. Saponification
Esterification: Carboxylic acid + Alcohol in presence of acid catalyst yields sweet-smelling Ester ($CH_3COOH + C_2H_5OH \xrightarrow{H^+} CH_3COOC_2H_5 + H_2O$). Saponification: Alkaline hydrolysis of esters with $NaOH$ yields soap ($CH_3COONa$) and alcohol.
