AIIMS 2019 Chemistry Geometric Isomerism MCQ Question
trans isomer has a high melting point because it is symmetrical due to closely packed structure and hence it also take more energy to melt.
Correct Answer
Detailed Explanation
Trans isomers exhibit higher melting points due to their symmetrical structure, which allows for efficient packing in the solid state, resulting in stronger intermolecular forces. This close packing requires more energy to overcome during the melting process. In contrast, cis isomers often have bulky groups that hinder close packing, leading to lower melting points. Thus, the statement correctly identifies the relationship between trans isomer symmetry and melting point.
