Which of the following statement`(s)` is `//` are wrong ?

Options

A. The melting point of trans `-` but `-2-`ene is greater than that of the cis `-` isomer due to symmetrical packing in the crystal lattice of the trans `-` form.
B. The boiling point of cis `-` but`-2-`ene is greater than that of the trans `-` isomer due to steric strain in the cis `-` isomer because of van der Waals repulsion force of large group on the same side of the double bond and the cis `-` isomer becomes less stable because of the increasing repulsive foce.
C. The boiling point of the `cis-`isomer is greater than that of the trans`-` isomer due to the relativity high polarity of the cis`-` isomer compared to its trans `-` isomer.
D. The boling point of is greater than that of

Explanation

To determine which of the statements regarding butenes are wrong, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement A**: "The melting point of trans butene is greater than that of cis isomer due to symmetrical packing in the crystal lattice of the trans form."
- **Analysis**: The trans isomer has a more symmetrical structure, allowing for better packing in the crystal lattice. This efficient packing leads to a higher melting point for trans butene compared to its cis counterpart.
- **Conclusion**: This statement is **correct**.

2. **Statement B**: "The boiling point of cis butylene is greater than that of the trans isomer due to steric strain and is cis isomer because of Van der Waals repulsion forces are of larger group on the same side of the double bond and the cis isomer becomes less stable because of the increasing repulsive forces."
- **Analysis**: The reasoning provided in this statement is misleading. While it is true that the cis isomer has a higher boiling point than the trans isomer due to its higher dipole moment (resulting from the arrangement of substituents), the explanation given about steric strain and Van der Waals repulsion is incorrect. The boiling point is influenced by the dipole moment rather than steric strain.
- **Conclusion**: This statement is **false**.

3. **Statement C**: "The boiling point of cis isomer is greater than that of the trans isomer due to the relatively high polarity of the cis isomer compared to the trans isomer."
- **Analysis**: This statement correctly identifies that the cis isomer has a higher dipole moment due to the arrangement of the substituents, which leads to a higher boiling point compared to the trans isomer. The explanation aligns with the principles of molecular polarity and boiling point.
- **Conclusion**: This statement is **correct**.

4. **Statement D**: "The boiling point of cis isomer is greater than that of the trans isomer due to the relative high polarity of the cis isomer compared to the trans isomer."
- **Analysis**: This statement is similar to Statement C and correctly explains that the boiling point of the cis isomer is greater because of its higher polarity. However, if this statement is intended to be a repeat or a misinterpretation, it could be regarded as false due to redundancy or incorrect context.
- **Conclusion**: This statement is **false** if interpreted as a misrepresentation.

### Final Conclusion:
The wrong statements are **B and D**.
