Solution

The correct option is B Both cis and trans isomers have a same melting point
Trans has a higher melting point than cis because of it' symmetric structure and so, it can be more closely packed in a crystal form. Therefore, it has higher melting point than the cis isomer.

Q. What is dipole moment? Why do cis-trans isomers have different boiling point?

Q. First, you name both the compounds. Yes, both of them have the same name. Yet, are they really the same structure, or they are somehow different? Careful inspection should convince you that they are indeed different. Now, how their physical and chemical properties differ? Generally,
i) Cis-isomer has more dipole moment than trans-isomer.
ii) Cis is less stable than trans.
iii) The boiling points of cis isomers are more than those of trans isomers (remember boiling points are directly related to polarity which is determined by dipole moment).
iv) Chemical reactivities of cis and trans also differ from each other.
