Therefore, the subject helps students understand molecular recognition, host-guest chemistry, self-assembly, biological models, supramolecular transport and molecular architectures.

The uploaded assignment identifies MCHE-013 as Supramolecular Chemistry and gives the assignment code MCHE-013/TMA/2026-27 with a maximum of 100 marks.

The programme category data also lists MCHE-013 as Elective-III: Supramolecular Chemistry under the MSCCHEM programme.

MCHE-013 Supramolecular Chemistry Course Information

MCHE-013 Solved Assignment 2026-27 Overview

The MCHE-013 Solved Assignment 2026-27 in English begins with important non-covalent interactions used in supramolecular chemistry. The assignment discusses dipole-dipole interactions, molecular recognition and the lock-and-key principle of binding.

Next, students study different supramolecular complexes along with enthalpy-driven and entropy-driven binding processes. The paper also covers clathrates, clathrands, cucurbiturils and calixarenes.

The assignment then explores cryptands and different types of hosts. In addition, it examines host-guest interactions, neutral receptors and molecular assemblies such as trimesic acid networks.

Biological self-assembly forms another major section. Students study minimal self-replication, Tobacco Mosaic Virus self-assembly, biological models and artificial photosynthesis.

Furthermore, the paper covers supramolecular catalysis, cocatalysis and molecular transport. It also introduces racks, ladders, grids and metal-organic frameworks.

Finally, students study catenanes, rotaxanes, supramolecular isomerism, polymorphism and rational design in supramolecular chemistry.
