Abstract: A variety of patterns are observed when carboxylic acids crystallize from aqueous solution admixed with agar agar or from alcoholic solutions. Oxalic acid crystallizes in fractal-like morphology with fractal dimension D =1.65. Succinic acid and adipic acids show tree-like and dendritic morphology respectively. The o- and p-amino benzoic acids show sheaf-like morphology, characteristic of spherulitic growth but o-toluic acid shows a radial branched pattern with fractal dimension D=1.53. Mandelic acid shows fractal-like mophology when crystallized from its alcoholic solution and concentric rings on crystallization from a dense aqueous medium. In the latter computer analysis shows periodicity in the number density of crystal nuclei (N) versus distance (r) plot.
