Step 1: Understanding Acidic Strength in Aliphatic Acids
Acidic strength is influenced by the inductive effect of alkyl groups. Alkyl groups are electron-donating ( effect), which increases the electron density on the carboxylate ion, making it less stable.

Step 2: Comparing the Acids
- HCOOH: No alkyl group, most stable conjugate base (strongest acid).
- : One methyl group ().
- : One ethyl group (stronger ).
- : One propyl group (strongest ).

Step 3: Correct Order
