Quick Recap — Named Reactions & Products

• Phenol: Kolbe $\to$ salicylic acid; Reimer-Tiemann ($CHCl_3$/NaOH) $\to$ salicylaldehyde; conc $HNO_3\to$ picric acid.
• Reductions: LiAlH$_4$/NaBH$_4$ (C=O $\to$ alcohol); Clemmensen (Zn-Hg/HCl) and Wolff-Kishner (C=O $\to$ CH$_2$); Rosenmund (acyl chloride $\to$ aldehyde).
• Etard ($CrO_2Cl_2$): toluene $\to$ benzaldehyde. Aldol (with $\alpha$-H) $\to$ $\beta$-hydroxy carbonyl $\to$ $\alpha,\beta$-unsaturated on heating.
• Acidity: carboxylic acid $>$ phenol $>$ water $>$ alcohol.
