We know that a reaction occurs spontaneously when ΔG<0 and that ΔG=ΔH-TΔS. So, we know that the reaction will be spontaneous when ΔH<TΔS.Its is given that ΔH and ΔS are <0 and that |ΔH|=3*|S|. Fr...

Unsaturated carbon chains contain one or more C-C double bonds. Due to the C-C double bonds, the chain is kinked which means it is not able to pack regularly which results in a lower melting point.
