To predict the product of a reaction involving Carboxylic Acids, one must identify the specific reagents and conditions provided in the reaction scheme (which is missing here).

Common reactions covered in NCERT Class 12, Unit 8 include:

1. Preparation: Oxidation of primary alcohols or aldehydes using common oxidizing agents ($KMnO_4$, $K_2Cr_2O_7$). Hydrolysis of nitriles ($R-CN$) or amides.

• Reaction of Grignard reagents with crushed dry ice ($CO_2$).

2. Chemical Properties:

• Acidity: Reaction with active metals and alkalies.
• Reduction: Reduction to primary alcohols using $LiAlH_4$ or $B_2H_6$ (diborane).
• Decarboxylation: Heating sodium salts of carboxylic acids with soda lime (NaOH + CaO) to remove $CO_2$ and form alkanes.
• Substitution: Halogenation of $\alpha$-hydrogen (Hell-Volhard-Zelinsky reaction) using $X_2$/Red P.
