Two Main Types Geometric Isomerism This happens when atoms are "locked" into a position, often around a rigid bond. One version might have two specific groups on the same side, while another version has them on opposite sides. Because the bond doesn't rotate easily, they stay stuck in those different shapes. Optical Isomerism This is exactly like the hand analogy. These are molecules that are mirror images of each other. Even though they look almost identical, their 3D shape is flipped. This is incredibly important in medicine, as one "shape" might cure a headache while the mirror-image "shape" does nothing at all. #neet2026 #chemistrypage #chemistry #jee #education #viral #physics #conceptneet #conceptneetacademy #conceptneetdigital #viralvideo #stereoisomerism #opticalisomerism #geometricisomerism #isomerism #chiralcarbon #goc #generalorganicchemistry #organicchemistry #rsconfiguration #eznomenclature #conceptmumbra #neetmumbra
