PPT-Relative Reactivities, Structures and Spectra of Carboxylic

201 Carboxylic acid derivatives undergo substitution reactions via the often acid or basecatalyzed additionelimination sequence The relative reactivities of the substrates follow a consistent order. 2. Introduction. The functional group of carboxylic acids consists of a C=O with -OH bonded to the same carbon.. Carboxyl group is usually written -COOH.. Aliphatic acids have an alkyl group bonded to -COOH.. . microlensing. on diffusive massive substructure. Sa. ša Simić. 1. and Luka Č. Popović. 2. ,3.

Carboxylic acids have much lower pK. a. values than do alcohols.. The lowered pK. a. values are due to the electron-withdrawing effect of the positively polarized carbonyl carbon and the resonance stabilization of the carboxylate group..
