SUMMARY
The discussion centers on determining which molecular structure has the highest melting point, focusing on the influence of intermolecular forces. Participants identify hydrogen bonding, dipole-dipole interactions, and London dispersion forces as key factors. The consensus emerges that structure A, which likely exhibits stronger intermolecular forces, is the correct answer, contrary to initial assumptions about structure C (1-butene). The conversation emphasizes the importance of understanding molecular features and their impact on melting points.
PREREQUISITES- Understanding of intermolecular forces: hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
- Basic knowledge of molecular structures and their properties.
- Familiarity with the concept of melting points in chemistry.
- Ability to analyze and compare molecular features.
- Research the characteristics of hydrogen bonding and its effect on melting points.
- Explore the differences between dipole-dipole interactions and London dispersion forces.
- Study the molecular structure of various hydrocarbons and their melting points.
- Learn about the role of molecular polarity in determining physical properties.
Chemistry students, educators, and anyone interested in molecular chemistry and the factors influencing melting points.

the forces:
hydrogen
dipoole-dipole
london dispersion
I am thinking C. am i right?
hydrogen
dipoole-dipole
london dispersion
I am thinking C. am i right?

Your are correct, but do you know why?

i believe B and C are dipole-dipole forces, which are stronger than A and D which are london disperion forces. i know dipole-diople is stronger than london. Would the answer be C since it has the longest carbon chain that is polar.
thanks
thanks

Keep working at it... "C" (1-butene) is NOT CORRECT!

In which case, I stand corrected. I guess I should stick to Math & Physics, and butt out of chem...

I did some research and i believe that the answer is A.
does that sound right?
