An … WebA carboxylic acid first adds to the DCC molecule to form a good leaving group, which can then be displaced by an amine during nucleophilic substitution to form the corresponding amide. The reaction steps are shown below: Step 1: Deprotonation of the acid. Step 2: Nucleophilic attack by the carboxylate. Step 3: Nucleophilic attack by the amine. harry potter diagon alley bookendsWebCČC bond angle 120. Outer electron 2p orbital of carbon overlaps with the same of other carbon to create a delocalised pi bond (in alkenes). In benzene a delocalised electron pi structure is formed from this 2p orbital overlapping. The 2p orbital is above and below the plane of carbons (8 shaped).

"Webthe carboxylic acid product is formed but NH2^- (called an azanide anion) is also formed. The azanide anion is a very strong base which is in the presence of a carboxylic acid which, as the name suggests, is acidic. This leads to an acid/base reaction to deprotonate the acid not necessarily because we want to but simply because it's unavoidable ... " - Lialh4 with carboxylic acid
