Straight Chain Saturated Monocarboxylic Acid
Nov 14, 2018

The melting point of straight chain saturated monocarboxylic acids with the increase of the number of C atoms in molecules are zigzag changes, including even the melting point of C atoms acid than the adjacent two odd number of C atoms acid high melting point, this is because in the even C atoms in the chain, the chain of methyl and carboxyl end points on either side of the chain, and in an odd number of C atoms in the chain, in the same side of the C chain, the former has higher symmetry, closer alignment, can make the lattice of carboxylic acid has great attraction between them, high melting point.
