Document Summary

Carboxylic acids are compounds with cooh group. Mo(cid:374)o(cid:272)ar(cid:271)o(cid:454)(cid:455)li(cid:272) a(cid:272)ids are (cid:374)a(cid:373)ed (cid:449)ith suffi(cid:454) (cid:862)oi(cid:272) a(cid:272)id(cid:863) (cid:894)e(cid:454)a(cid:373)ple, (cid:271)uta(cid:374)oi(cid:272) acid). The parent chain is the longest chain that includes the carbon of the carboxylic acid group, which is assigned the number 1. If the carboxylic acid group is connected to a ring, the compound is named as alkanecarboxylic acid (example, cyclohexanecarboxylic acid). Many common names are accepted by iupac (example, formic acid, acetic acid, benzoic acid). Dia(cid:272)ids (cid:894)(cid:272)o(cid:374)tai(cid:374) t(cid:449)o cooh groups(cid:895) are (cid:374)a(cid:373)ed (cid:449)ith the suffi(cid:454) (cid:862)dioi(cid:272) a(cid:272)id(cid:863) (cid:894)e(cid:454)a(cid:373)ple, pentanedioic acid. There are also many dioic acid common names accepted by iupac; they are used for the study of biochemical reactions so they should be committed to memory. The carbon atom of the carboxylic acid group is sp2 hybridized and thus has trigonal planar geometry (bond angle 120 ). Molecules can form two hydrogen-bonding interactions, leading to the relatively high boiling points of carboxylic acids.
