(a)
Interpretation:
The IUPAC name of reaction products when ethyl pentanoate undergoes ester hydrolysis under acidic conditions has to be written.
Concept Introduction:
Breaking of the carbon‑oxygen single bond present between the “acid part” and “alcohol part” is one of the important reactions of ester. This process of breaking the bond between the carbon‑oxygen is known as ester hydrolysis or saponification. The condition prevails in the reaction determines it as ester hydrolysis of saponification.
Ester hydrolysis takes place in ester when it is treated with strong acid or enzymes as catalyst. Reverse of esterification reaction is the ester hydrolysis.
Saponification is the reaction that ester undergoes when a strong base is used to give the product as
