Optical activity class 12 chemistry
WebOptical activity: Optical activity is the property of certain organic substances to rotate the plane of plane polarised light towards the right (clockwise) or towards the left … WebSolution Verified by Toppr Optical Activity: Compounds that rotate the plane of polarized light are called optically active compounds and this property is known as optical. CH 3−CH 2− C∗H−CH 3 & CH 3− C∗H−COOH ∣ ∣ Br OH are optically active compounds because they both have one chiral centre. Solve any question of Haloalkanes and Haloarenes with:-

WebDec 15, 2024 · 5.4: Optical Activity. The two enantiomers are mirror images of each other. They are very alike and share many properties in common, like same b.p., m.p., density, color, solubility etc. In fact, the pair of enantiomers have the same physical properties except the way they interact with plane-polarized light. WebDec 18, 2015 · 12. Optical activity is common in biochemistry and pharmaceuticals. * Most amino acids exhibit optical activity * Many drugs must be made of one optical isomer to be effective - Need smaller doses (safer and cost effective) - Get reduced side effects - Improved pharmacological activity Importance ofOpticalIsomerism : 13.
