ChemistryEasysingle choice

Arrange the melting points of following compounds in decreasing order
$1 .$ n-butane
$2 .$ cis-2-butene
$3 .$ trans-2-butene
$4 .$ 1-butyne

Options:

Answer:

Solution:

Melting point $\propto$ molecular weight, symmetry of the molecule
$\propto \frac{1}{μ}$ of the compound. $(μ = dipole moment)$
Hence the correct order of melting point is
1-butyne > trans-2-butene > cis-2-butene > n-butane.
