Stereoisomers have the same structural formula and molecular formula but a different arrangement in space
Optical isomers are two non superimposable mirror images of each other
A optical isomer must have a carbon atom with 4 different groups attached known as "Chiral" Carbon or asymmetric carbon
Simple substances that show optical isomerism exits as two isomers known as enantiomers
A Racemic mixture is formed when a equal concentration of each enantiomer is formed due to equal attack from either side of the planarcarbonyl bond, enantiomers rotate light equally in opposite directions therefore no overall rotation
Optical isomers show different behaviours in plane polarised light, they rotate light in opposite directions
Answer:
Q1.
Q2. Use Plane polarised light (1)
rotates (the plane of) in opposite directions (2)
Question
Answer
a, 2-hydroxyhexanenitrile
b, (Plane) polarised light (1)
Enantiomers would rotate light in opposite directions(2)
Questions
Answer
Planar (1)
Attack from either side (2)
With equal probability OR produces equal amounts (of the two isomers/enantiomers (3)
