What is the reason behind the irregularity of the melting point of the alkanes??

Re: Organic Chemistry: Alkanes
the bigger the molecule is the more are bonds.and, we need more heat to break them.that's why
\[\sum_{k=0}^{n-1}e^{\frac{2 \pi i k}{n}}=0\]

Re: Organic Chemistry: Alkanes
U see, melting point increases from c-1 to c-2 and again drops from c-2 to c-3. then again increases then decreases. here c-2 denotes the Alkane with 2 carbon atoms. I was asking for the reason that will explain this irregularity

Ethane, propane and n-butane form layer structures in the solid state. By describing their molecular geometries as a rectangle, an irregular pentagon and an irregular hexagon, respectively, it is shown here that propane cannot close-pack like its congeners. The melting point of propane is therefore lower than expected in the series.

Re: Organic Chemistry: Alkanes
as my chemistry teacher said one who is proficient in organic chemistry he knows stereo chemistry very well. and i think that is nothing but physics s o all the proper explanation lies in physics
