Practice BITSAT Aldehydes, Ketones and Carboxylic Acids in the app →The functional group $>\!\mathrm{C}\!=\!\mathrm{O}$ that is common to aldehydes, ketones, carboxylic acids andReduction of an aldehyde with $\mathrm{NaBH_4}$ or $\mathrm{LiAlH_4}$ produces:Which reagent distinguishes aldehydes from ketones by giving a positive (silver mirror) reaction only with aldThe aldol condensation requires which structural feature on the carbonyl compound?Benzaldehyde is treated with concentrated $\mathrm{NaOH}$ (Cannizzaro reaction). The products are:Arrange in **decreasing** order of acidic strength: $\mathrm{CH_3COOH}$, $\mathrm{FCH_2COOH}$, $\mathrm{CF_3COFunctional group of aldehyde:Functional group of ketone:Functional group of carboxylic acid:Carbonyl carbon hybridization:IUPAC name of CH₃CHO:Fehling's test positive for:Nucleophilic addition to carbonyl: nucleophile attacks:Reduction of aldehyde RCHO by NaBH₄ gives:For α,β-unsaturated ketones (enones), 1,4-addition (Michael) competes with 1,2-addition. Soft nucleophiles preClemmensen reduction converts C=O to CH₂ using:Esterification: RCOOH + R'OH + acid catalyst yields:In Friedel-Crafts acylation, RCOCl + AlCl₃ + benzene gives:Glycine has 2 amino acid forms in solution. Zwitterion:
