Which of the following is correct set of physical properties of the geometrical isomers?
\( ^{CH_3}_H>C = C<_{Cl}^H\) I
\( ^{CH_3}_H>C = C<_H^{Cl}\) II
Dipole - B.P. - M.P. - Stability moment
(a) I > II - I > II - II > I - I > II
(b) II > I - II > I - II > I - II > I
(c) I > II - I > II - I > II - I > II
(d) II > I - II > I - I > II - I > II

Correct answer: (c) I > II - I > II - I > II - I > II
Explanation:
In compounds
I has more dipole moment than II, hence its boiling point will be higher. Melting point depends on symmetry, therefore I has higher melting point than II. Steric crowding in II is more than in I therefore I is more stable than II.
