Draw cis and trans isomers of pent-2-ene. Which isomer will have higher melting point and why?
The cis and trans isomers of pent-2-ene are as follows:
The cis-isomer is more polar than trans-isomer. The dipole moment of cis-isomer is higher than trans-isomer. Due to higher polarity, cis-isomer form stronger interparticle bonding and require more energy to break the bonds. Hence cis-isomer have higher melting point.
