Give reason for the following:
The melting point of $$cis-2-butane$$ is lower than that of $$trans-2-butane.$$
Thus, trans alkenes, which are less polar and more symmetrical, have lower boiling points and higher melting points, and cis alkenes, which are generally more polar and less symmetrical, have higher boiling points and lower melting points.
Hence , The melting point of cis−2−butane is lower than that of trans−2−butane.
