Isomerism

Question 1

Isomerism

Answer 1

Occurrence of compounds having identical compositions but different structures

Question 2

Structural isomerism

Answer 2

Atoms are connected differently

Question 3

Stereoisomeism

Answer 3

Atoms are arranged differently in space, can be geometrical or optical

Question 4

Geometrical isomerism

Answer 4

Occurs when there is no free rotation
Cis if groups r on the same side
Trans if groups r on opp sides

Question 5

Optical isomerism

Answer 5

Isomers are 2 mirror images that are not superimposable, and have a chiral carbon atom
Levorotay if group is on the left
Dextrorotatory if group is on the right

Question 6

Enantiomers

Answer 6

Pair of optical isomers

Question 7

Racemic mixture

Answer 7

Equimolar mixture of optical isomers that doesn’t rotate a plane polarized light
