A2 Optical isomerism

Question 1

optical isomerism

Answer 1

when 4 functional groups are attached to the chiral centre which results in mirror image non-identical non-superimposable isomer

Question 2

structural isomerism

Answer 2

different functional group
different chain
different position of functional group

Question 3

stereoisomerism

Answer 3

they have the same structural formula but atoms are arranged differently across the plane

Question 4

types of stereoisomerism

Answer 4

E Z isomerism

optical isomerism

Question 5

optical isomerism and plane polarised light

Answer 5

optical isomers can rotate plane polarised light in opposite anticlockwise vs clockwise

Question 6

chiral

Answer 6

carbon is bonded to four different groups and is not symmetrical

Question 7

optical isomers name

Answer 7

enantiomers

Question 8

ordinary light goes

Answer 8

all directions

Question 9

what happens if light passes through a polaroid

Answer 9

light vibrate on a vertical plane

Question 10

polarised light

Answer 10

there are equal conc and volume of optical isomers, this is causes light to rotate one direction and one the other,

Question 11

racemates

Answer 11

contains equal quantities of optical isomers
it does not show any optical activity
as isomers cancel rotation effect of each other
