Molecule But Different Shape Flashcards
Optical isomerism
Terra deal carbon Mirror images Enationers Derived enantio means opposite Different atoms groups attaches
Isomers
2 or more different compounds
Structural isomerism and stereoisomers
Struc - functional groups and different ways ml
Stere- the geometrical positioning of atoms In space differs
Optical isomerism mirror images
Geometric isomerism can be twisted ways
Cont
Identical chemical and properties
Distinguished
Rotate plane polarised
Opposite directions md isomers will rotate plane polarised
Cont
Sugars can also exist in d and l Forms
Glyceradlehyde
One asymmetric carbon with aldehyde group
Chiral carbons increase
Cont
Isomers increase
Carbon is reversed
D glucose and d galactose as disstereomers and there not mirror images
Cont
Stereisomers becomes apparent as anomers
Glucose undergoes nuts rotation
D glucose cyclises firms a d glucose
Anomeric carbon
Geometric isomerism
Cis trans isomerism
Has carbon carbon double bond
Methyl has double bond cis isomers.
Trans- isomers released in opposite sides
Cont
Cis config causes kink Trans config forms straight chain Unsaturated oils are CIs bonds Cis bonds to convert to trans Exposure to light release and asborbs photon
