Melting point of benzenecarboxylic acid

WebThis reflects differences in intermolecular attractive forces in the crystalline state. In the table of fatty acids we see that the presence of a cis-double bond significantly lowers the melting point of a compound. Thus, palmitoleic acid melts over 60º lower than palmitic acid, and similar decreases occur for the C 18 and C 20 compounds. Web17 okt. 2007 · The naphthalene was weighed at 0.035 g and its melting point was 76 ºC. III. Conclusions The compounds extracted seem to be slightly impure. The melting points for benzoic acid, p -nitroaniline, and naphthalene that were found are all slightly lower than the melting points I looked up beforehand.
