Carboxylic Acid Structure Thegeneral formula of a carboxylic acid is R-COOH, where COOH refers to the carboxyl group, and R refers to the rest of the molecule to which this group is attached. In this carboxyl group, there exists a carbon which shares a double bond with an oxygen atom and...
{/eq}). The carboxylic acid structure is best described astrigonal planar. That is because the carbon and the oxygen in the carbonyl group are both {eq}sp^2 {/eq} hybridized. The hydroxyl group also exhibits the same hybridization as the carbonyl group, which enables one of its electron ...
羧酸（Carboxylicacids）新编有机化学 235 5.2羧酸 5.2.1 羧酸的结构特征 含有羧基（-CO 2H ）官能团的化合物称为羧酸。羧基组成中含一个羰基和一个羟基，但它的性质与只含有羰基的醛酮有较大差异。这是由于羧酸中羰基（C=O ）п轨道与羟基（OH ）氧上的p 轨道发生p-π共轭，从而消弱了C=O 双键，增强...
