Correct Answer - `(##NCERT_CHM_V02_XI_C13_E01_009_A01##)`
The cis form will have higher boiling point due to more polar nature leading to stronger intermolecular dipole-dipole interaction, thus requiring more heat energy to to separate them.
Hex-2-ene is represented as: `H_(3)C-HC=CH-CH_(2)-CH_(3)` Geometrical isomers of hex-2-ene are:
The dipole moment of cis-compound is a sum of the dipole moments of `C–CH_3 "and" C– CH_2CH_3` bonds acting in the same direction.
The dipole moment of trans-compound is the resultant of the dipole moments of `C–CH_3 " and " C–CH_2CH_3` bonds acting in opposite directions.
