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:
