Isomerism Flashcards
(12 cards)
Structural Isomers Examples
chain
positional
functional group isomers
Stereoisomers Examples
E-Z
Optical
Functional Isomers
same molecular formula but different structural formula with a different functional group
Optical Isomers
molecules that exist as non-superimposible mirror images
Optically Active
A sample which rotates the plane of plane polarised light
Chiral Centre
an atom that has 4 different atoms or groups attached
What does no chiral centre mean
Optically Inactive
Types of Optical Isomers
d - dextrorotary - rotates plane of ppl to the RIGHT
l - laevorotary - rotates plane of ppl to the LEFT
Racemic Mixture
A 50:50 mixture of two optical isomers
Why are some drugs optical isomers more effective
how isomers bind to receptor sites which are specific to one isomer
Why are recepetor sites stereospecific
due to functional groups that are present are present in the site
Why are anaesthetics administered as racemic mixtures
isoflurane
no harmful effects from other isomer
more expensive if they were seperated
