Step 1
Determine the structural characteristics of the molecules
Answer
To assess the melting points of molecules X, Y, and Z, we first analyze their structures. The presence of double bonds and branching in these molecules can significantly affect their melting points, as they influence molecular packing and intermolecular forces.
Step 2
Evaluate the melting points
Answer
- Molecule Y, having less branching and possibly more linear characteristics, is likely to have the highest melting point due to better packing in solid state.
- Molecule Z, while also having some linearity, likely has a moderately lower melting point than Y due to its structural features.
- Molecule X, likely being the most branched or having the most double bonds, will have the lowest melting point due to poorer packing and weaker van der Waals forces.
