Subrata: Sengupta Stereochemistry

| Parameter | Classical Models (Cram, Felkin-Anh) | Sengupta’s Refinements | |-----------|--------------------------------------|-------------------------| | | Steric bulk only | Steric + electrostatic | | Predictive scope | Limited to simple acyclic systems | Extended to β-heteroatom carbonyls & cyclic transition states | | Experimental validation | Extensively validated (1960s–80s) | Moderate validation (1990s–2000s); requires more computational testing | | Pedagogical clarity | High but abstract | High with practical mnemonics |

Dr. Subrata Sengupta is a prominent figure in the world of Indian chemical education. He earned his Ph.D. from Calcutta University and spent over three decades teaching at RPM College, an affiliate of Calcutta University. His work is highly regarded for bridging the gap between foundational concepts and the advanced spatial reasoning required for competitive exams like JAM, GATE, and CSIR NET.

One of the greatest hurdles in learning stereochemistry is the cognitive leap required to translate two-dimensional drawings on a blackboard into three-dimensional realities in the mind. from Calcutta University and spent over three decades
