Decane-1,10-dioic acid

One after the other, examine structures for octane-1,8-dioic acid, nonane-1,9-dioic acid djud decane-1,10-dioic acid. Is there any difference (in structure or conformation) between the diacids with lower and higher melting points Which, if any, of the acids adopt structures similar to that of acetic acid dimer Account for the variation in melting points of these three compounds. 

Undecylenic acid (10-undecenoic acid), when treated with potassium permanganate and sodium periodate in an aqueous solution of potassium carbonate at 20 °C for 20 h, gives sebacic acid (decane dioic acid) in 73% isolated yield [763]. A similar oxidation of oleic or elaidic acid yields a mixture of pelargonic acid and azelaic acid [763] (equation 474).
