Heating calcium propanoate ((CH₃CH₂COO)₂Ca) forms pentan-3-one (CH₃CH₂COCH₂CH₃) and releases CO₂ as a byproduct.

LiAlH₄ reduces carboxylic acids to primary alcohols. Propanoic acid (CH₃CH₂COOH) yields propan-1-ol (CH₃CH₂CH₂OH).

Step 1: LiAlH₄ reduces propanoic acid (CH₃CH₂COOH) to propan-1-ol (CH₃CH₂CH₂OH). Step 2: PCC oxidizes it to propanal (CH₃CH₂CHO), not ethanal. However, the closest two-step process aligns with reduction then oxidation, corrected contextually.

Propanoic acid (CH₃CH₂COOH) reacts with SOCl₂ to form propanoyl chloride (CH₃CH₂COCl).

Acidity increases with electron-withdrawing groups: CH₃CH₂COOH (alkyl) < CH₃COOH < CH₂FCOOH (F enhances acidity).

Propan-1-ol (CH₃-CH₂-CH₂OH), a primary alcohol, is oxidized to propanoic acid (CH₃-CH₂-COOH) with a strong oxidizing agent like alkaline KMnO₄.
